Wang zijun ( condensed matter physics ) directed by prof . zhong guozhu and li wenlian hotly studied organic thin film electroluminescence , because of its ultra high brightness and efficiency , reminds man to consider the possibility of realizing organic semiconducting laser diods 热点研究的有机薄膜电致发光，由于极高的亮度和效率，使人联想有机半导体薄膜激光二极管的可能性。率先的突破是在单晶上作出的，用了场效应注入双电极。
Its potential and maximal application field is for semiconductor films and optic films that mainly rely on the high - orientation and single crystal diamond films and big area transparent diamond films . but it is widely existent for defects in the process of diamond films growth and also it is difficult to get parameters stability such as temperature etc in wide area , as a result , the diamond films " orientation is changed , and it is very difficult to get the high - orientation and single crystal diamond films and big area transparent diamond films 金刚石膜潜在的最大应用领域是作为半导体薄膜和光学薄膜，而这个领域的开发在很大程度上依赖于高取向和单晶金刚石薄膜以及大面积透明金刚石膜的获得，但由于金刚石膜生长过程中缺陷的普遍存在以及大面积范围内均匀温度场等参数的难以获取，从而导致金刚石膜的取向发生改变，使高取向和单晶金刚石薄膜以及大面积透明金刚石膜的获得十分困难。
The tio2 , cds and cds - tio2 films on the common glass substrate were prepared , respectively , using ti ( oc4h9 ) 4 , cd ( cooch3 ) 2 and scn2h4 as raw materials by sol - gel method . the influences of manifold preparing parameters ( such as the concentration of sol , the amount of the peg . the number of coatings , the heat - treated temperature and time ) on the structure and performance were studied 本文采用溶胶-凝胶技术，以钛酸丁酯、乙酸镉和硫脲为原料，以普通玻璃片为载体，制备了纳米tio _ 2薄膜、 cds薄膜和cds - tio _ 2复合半导体薄膜，研究了制备过程中多种制备参数(如溶胶的浓度，聚乙二醇( peg )的加入量，镀膜层数，热处理温度及时间)对薄膜结构和性能的影响，采用x -射线衍射( xrd ) 、扫描电镜( sem ) 、能谱分析( edxa ) 、紫外-可见吸收光谱( uv - vis )等测试手段对各薄膜进行了结构和物性表征。
