本工作以三乙烯四胺、乙二胺、N，N-二甲基甲酰胺和三乙醇胺为助剂，CuCl_2中心点2 H（2）O、InCl_3中心点4 H（2）O、GaCl_3和Se粉为前驱体，N_2H_4中心点H_2O为还原剂，聚乙烯吡咯烷酮为分散剂，制备了三元和四元黄铜矿CuIn 1-xGaxSe 2纳米晶（0
In this work, four organoalkali-assisted diethylene glycol solution chemical syntheses, using triethylenetetramine, ethanediamine, N,N-dimethylformamide and triethanolamine as assisting agents, CuCl2 center dot 2H(2)O, InCl3 center dot 4H(2)O, GaCl3 and Se powder as precursors, N2H4 center dot H2O as the reductant and polyvinylpyrrolidone as the dispersant, were applied to prepare ternary and quaternary chalcopyrite CuIn1-xGaxSe2 nanocrystals (0
