采用溶剂热一锅法，在较低温度（150-180°C）下，通过氯化铟和三（二甲氨基）膦的热分解反应制备了单分散的InP纳米晶。尺寸选择性沉淀后的InP纳米晶体具有结晶良好的锌尖晶石结构，窄的尺寸分布，和可区分的吸收峰。HF处理结合光刻的应用将其发射效率提高到58%，同时其发射波长可从绿色到红色调谐。
Monodisperse InP nanocrystals were prepared by a facile one-pot solvothermal route via the pyrolysis reaction between indium chloride and tris(dimethylamino)phosphine at relatively low temperatures (150-180°C). The InP nanocrystals after size-selective precipitation had a well-crystallized zinc blende structure, a narrow size distribution, and distinguishable absorption peaks. Application of HF treatment in combination with photoetching increased their emission efficiency to 58% while their emission wavelengths were tunable from green to red.
