Influence of annealing on microstructure and properties of Cr-doped ZnO thin films deposited on glass surface ×÷Õß:Fu, CF (Fu, Chang-Feng)[ 1 ] ; Han, LF (Han, Lian-Fu)[ 1,2 ] ; Liu, C (Liu, Chao)[ 1 ] ; Sun, T (Sun, Tao)[ 3 ] ; Liu, XB (Liu, Xing-bin)[ 2 ] JOURNAL OF MATERIALS SCIENCE-MATERIALS IN ELECTRONICS ¾í: 28 ÆÚ: 4 Ò³: 3812-3818 DOI: 10.1007/s10854-016-5992-1 ³ö°æÄê: FEB 2017 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª Cr-doped ZnO thin films were deposited onto glass substrates by radio frequency magnetron sputtering technique. The effects of annealing temperature and annealing time on the structural and optical properties of the Cr-doped ZnO films were comprehensively investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV) and photoluminescence (PL) measurements. XRD studies reveal that the Cr-doped ZnO films are highly oriented along (002) direction. The intensity of ZnO (002) peak firstly increases and then decreases with increasing annealing temperature and annealing time. SEM analysis show that the grain size increases and the surface of films becomes rougher as the annealing temperature increases to 700 A degrees C. The optical transmittance spectra indicate that the average transmittance in the range of the visible region is approximately 80%, and the band gaps of the films decrease with increasing annealing temperature. Two peaks of UV emission and green emission are observed in the PL spectra. The UV emission increases first and then decreases with increasing annealing temperature, which show that the increasing defect concentration in the films leads to the poor crystallinity. The green emission greatly increases with increasing annealing temperature, which could be attributed to the increase of oxygen vacancies and increased nonradiative process. ¹Ø¼ü´Ê KeyWords Plus:SOL-GEL METHOD; PULSED-LASER DEPOSITION; OPTICAL-PROPERTIES; VARISTOR CERAMICS; ROOM-TEMPERATURE; PHOTOLUMINESCENCE; FERROMAGNETISM ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Liu, C (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ Northeast Petr Univ, Sch Elect Sci, Daqing 163318, Peoples R China. µØÖ·: ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 1 ] Northeast Petr Univ, Sch Elect Sci, Daqing 163318, Peoples R China [ 2 ] Daqing Oilfield Ltd Co, Postdoctoral Res Ctr, Daqing 163453, Peoples R China ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 3 ] ASTAR, Inst Microelect, Singapore 117685, Singapore µç×ÓÓʼþµØÖ·:msm-liu@126.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ Natural Science Foundation of China 51474069 51101027 51374072 Youth Science Foundation of Northeast Petroleum University NEPUQN2014-8 Program for Science and Technology Study in Education Department of Heilongjiang province 12541053 12541096 Program for New Century Excellent Talents in Heilongjiang Provincial University 1253-NCET-002 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Àà±ð / ·ÖÀà Ñо¿·½Ïò:Engineering; Materials Science; Physics Web of Science Àà±ð:Engineering, Electrical & Electronic; Materials Science, Multidisciplinary; Physics, Applied; Physics, Condensed Matter ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000394352600087 ISSN: 0957-4522 eISSN: 1573-482X ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: EL1AJ Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 27 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 Çë¼û¸½¼þ |
