第一句：While, the most commonly used method is to physically mixed phosphors: yellow/red phosphors, green/red phosphors, or green/yellow/red phosphors [5-7]. So, it’s urgently needed to find novel green or red-emitting phosphor. 楼主疑问：上面句子是不是 is to physically mixed 改成is to physically mix ，去掉mixed 后面的ed?还是其他地方有问题？ 第二句：However, because the emission spectra of these phosphors absences in the red region, so YAG: Ce based white LED has a poor color rendering index (CRI). 楼主疑问：这句楼主只发现because和so 的错误，还有其他错误么？ 第三句：After fully grinding, small amounts powder were putted into an alumina crucible in a tube furnace and slowly heated to 1400℃ under a reducing atmosphere (5% H2+95% N2). 楼主疑问：楼主实在找不出这句有什么疑问？难道是put的被动语态用错了？ 第四句： the characteristic peaks are at 2θ =12.87°, 25.98°, 31.98°. X-ray diffraction patterns of doped Eu2+ are in good agreement with the X-ray diffraction which is reported by Lee et al, 楼主疑问：改成The characteristic peaks are at 2θ =12.87°, 25.98°, 31.98°, which agree well with the phase reported by Lee et al, 第五句：The peak position shifts to long wavelength when the Eu2+ concentration is more than a critical concentration, which can be demonstrated as red-shift 楼主疑问which can be demonstrated as red-shift这个句式对么，demonstrated后面能否加as? 第六句：It can be seen clearly that the enhancement of Ce3+ co-doped SrSiON:Eu2+ is about 140% compared with the one without Ce3+ co-doped. 楼主疑问：句子意思是加入Ce亮度提高140%，这句这样改对么，with 后面的 co-doped是否加ing 第七句：It is because of the energy transformation from Ce3+ to Eu2+ in the host lattice of phosphor samples. 楼主疑问：总觉的because of 在这里用不好，应该用attribute to？ 第八句：Consequently, Ce3+ and Eu2+ ions are acted as a sensitizer and an activator, respectively. 楼主疑问：Consequently, Ce3+ and Eu2+ ions act as a sensitizer and an activator, respectively.好还是上面一句好？ 第九句：Therefore, the electric dipole-dipole interaction predominates in the ET mechanism is from Ce3+ to Eu2+ in SrSiON: Eu2+,Ce3+. 楼主疑问： is from Ce3+ to Eu2+ in SrSiON: Eu2+,Ce3+ from前面要加 is 么？ 第十句：The 4f→5d transition of Ce3+ and Eu2+ ions is allowed . So the energy transfer from Ce3+ to Eu2+ ions is predominantly due to the electric dipole-dipole interaction according to the theory of energy transfer[13 楼主疑问：楼主的师兄觉得这句有问题，这句是楼主引用的理论，楼主实在看不出语法有什么错误? 第十一句：Therefore, the R of ET was calculate to be about 25.44Å. 楼主疑问：这句话是不是时态的问题？ |

第一句：个人意见is to physically mix 第三句：small amounts 后加上of 第五句：可以吧。例句 英文 This region is demonstrated as a geochemical region with high fluorine through studies on the fluorine contents of soils,magmatic rocks and the Archean?Cenozoic strata geochemical profile. 翻译 通过该区太古界一新生界氟的地层地球化学剖面及岩浆岩和土壤中氟的丰度的研究，论证了该区为一高氟的地球化学区。 第七句：我也不知道。但是有例句It was because of the job that he had taken the flat. 他因为工作的原因租了那套公寓 第八句：下面那句吧，不需要用被动吧。 第十一句：calculate应该 改为calculated吧 |

今天没心情工作，就和你讨论一下你的这些句子 第一句：While, the most commonly used method is to physically mixed phosphors: yellow/red phosphors, green/red phosphors, or green/yellow/red phosphors [5-7]. So, it’s urgently needed to find novel green or red-emitting phosphor. The most commonly used method is via physical mixing phosphors, such as yellow/red phosphors, green/red phosphors, or green/yellow/red phosphors [5-7]. So, it’s urgent to search for novel green or red-emitting phosphor. 第二句：However, because the emission spectra of these phosphors absences in the red region, so YAG: Ce based white LED has a poor color rendering index (CRI). However, these phosphors lack the red region in their emission spectra of , therefore YAG: Ce based white LED has a poor color rendering index (CRI). 第三句：After fully grinding, small amounts powder were putted into an alumina crucible in a tube furnace and slowly heated to 1400℃ under a reducing atmosphere (5% H2+95% N2). Small amounts of fully ground powder were put into an alumina crucible in a tube furnace and slowly heated to 1400℃ under a reducing atmosphere (5% H2+95% N2). 第四句： the characteristic peaks are at 2θ =12.87°, 25.98°, 31.98°. X-ray diffraction patterns of doped Eu2+ are in good agreement with the X-ray diffraction which is reported by Lee et al, The characteristic peaks are located at 2θ =12.87°, 25.98°, 31.98°, which agree well with the observation by Lee et al, 第五句：The peak position shifts to long wavelength when the Eu2+ concentration is more than a critical concentration, which can be demonstrated as red-shift The peak position shifts to long wavelength when the Eu2+ concentration is above certain critical concentration, which can be demonstrated as red-shift 第六句：It can be seen clearly that the enhancement of Ce3+ co-doped SrSiON:Eu2+ is about 140% compared with the one without Ce3+ co-doped. 应该写明具体是什么增加了，折中表达法很不合理 第七句：It is because of the energy transformation from Ce3+ to Eu2+ in the host lattice of phosphor samples. It is attributed to the energy transformation from Ce3+ to Eu2+ in the host lattice of phosphor samples 第八句：Consequently, Ce3+ and Eu2+ ions are acted as a sensitizer and an activator, respectively. Consequently, Ce3+ and Eu2+ ions act as a sensitizer and an activator, respectively. 第九句：Therefore, the electric dipole-dipole interaction predominates in the ET mechanism is from Ce3+ to Eu2+ in SrSiON: Eu2+,Ce3+. 这句话很难看懂，句子结构不合理 第十句：The 4f→5d transition of Ce3+ and Eu2+ ions is allowed . So the energy transfer from Ce3+ to Eu2+ ions is predominantly due to the electric dipole-dipole interaction according to the theory of energy transfer[13 The 4f→5d transition of Ce3+ and Eu2+ ions is allowed 是后面的理由吗？好像不合理 第十一句：Therefore, the R of ET was calculate to be about 25.44Å. Accordingly, the R of ET was calculated to be about 25.44Å. |

第二句：However, because the emission spectra of these phosphors absences in the red region, so YAG: Ce based white LED has a poor color rendering index (CRI). However, these phosphors lack the red region in their emission spectra of , therefore YAG: Ce based white LED has a poor color rendering index (CRI). 楼主疑问：是不是of 应该移到lack 后面：However, these phosphors lack of the red region in their emission spectra , therefore YAG: Ce based white LED has a poor color rendering index (CRI). 第六句： It can be seen clearly that the enhancement of Ce3+ co-doped SrSiON:Eu2+ is about 140% compared with the one without Ce3+ co-doped. 应该写明具体是什么增加了，折中表达法很不合理 楼主疑问：改成这样可以么：It can be seen clearly that the luminescent properties of SrSiON:Eu2+ ,Ce3+ phosphor are enhanced about 140% compared with the one without Ce3+ co-doped. 第九句：Therefore, the electric dipole-dipole interaction predominates in the ET mechanism is from Ce3+ to Eu2+ in SrSiON: Eu2+,Ce3+. 这句话很难看懂，句子结构不合理 楼主疑问：改成这样可以么，Hence, the energy transfer from Ce3+ to Eu2+ ions is predominantly attributed to the electric dipole-dipole interaction. |
