中文摘要：

采用单前驱体热解法、高温微乳液法合成了高质量的CdSe纳米晶，将CdSe纳米晶按照一定比例与聚苯乙烯撑（MEH—PPV）共混制成光电池，利用TEM、XRD等研究了纳米晶的形貌结构特征，结果显示，所合成的半导体CdSe纳米晶为闪锌矿结构，直径在3-5nm之间，复合光电池最好的器件能量转化达到0．85％，

英文摘要：

High quality CdSe nanocrystals can be prepared by thermolysing single precursor （kalium ethylxanthate） in hexadecylamine and high temperature microemulsion. Blend of modified CdSe nanoerystals with MEH-PPV in accordance with a particle number ratio. Transmission Electron Microscopy （TEM） and X-Ray Diffraction （XRD） were used to characterize the morphology. Tile results showed that the synthesis of CdSe semiconductor nanoerystals for the sphalerite structure, 3-5 nm in diameter, composite photovohaic energy conversion devices best to reach 0.85 percent.
