木虫之王 (文学泰斗)

[求助] 求汉译英一句话,谢谢大家!

近些年,稀土掺杂的纳米晶体的近红外到可见上转换发光成为了重要的科学热点,主要是由于它在生物荧光、激光器、太阳能电池和三维固体彩色显示器等方面有很大的潜在应用。而利用贵金属的表面等离子体共振与稀土上转换材料耦合实现上转换发光的增效是一种非常有效的手段。我们通过特殊的方法合成贵金属-稀土纳米材料的复合结构。在合成材料的过程中控制反应温度,颗粒尺寸的大小,以及反应时间的变化来提高贵金属的场增强效应,增强金属纳米粒子的尺寸以增加散射与吸收比,调控 LSPR 的位置与激发场相匹配,降低激发功率密度以抑制饱和效应与局域热效应,对获得高倍的 UCL 增强都十分重要。

5)        Recently, there has been many research activities in the field of  NIR to visible light upper-conversion using rare earth doped nanocrystals. This is mainly because its huge application potential in biofluorescence, laser devices, solar cells and 3-D colored display, etc.  The combination of   noble metal surface Plasmon resonance coupled with rare earth upper-conversion material  is a very effective method to enhance the efficiency of light emission by upper-conversion.  We synthesized the compound structure of noble metal-rare earth nano materials through a unique method. We found that it is important to control the reaction temperature, particle size, and reaction time to improve the field enhancement effect of noble metal. We also found that increased sizes of metal nanoparticles led to increased ratio between scattering and absorption.  One can carefully adjust the location (or position) of LSPR in order to match it with excitation field. By lowing (or reducing) the power density of the excitation light , we can suppress the saturation effect and local heat effect. All these variables are crucial to achieve a significant enhancement of UCL.
离成功还差一点
