采用一步溶剂热法制备了具有绿色发光的有机硅烷功能化碳量子点。采用无水柠檬酸和N-（2-氨乙基）-3-氨丙基三甲氧基硅烷（KH 792）制备SiCD。由于绿色SiCD用于将蓝光转换为绿色光，因此通过将发射450 nm的蓝光LED芯片和绿色SiCD组合来制造绿色发光二极管（LED）。绿色LED的发光效率可以达到60.96 lm/W。这种可聚合SiCD有望为简化制备工艺和提高绿色LED的光学性能提供新的契机。
Organosilane-functionalized carbon dots (SiCDs) with green emission were prepared by one-step solvothermal method. Anhydrous citric acid and N-(2-aminoethyl)-3-aminopropyltrimethoxy-silane (KH792) were used for the preparation of SiCDs. Green light-emitting diodes (LEDs) were fabricated by combination of a 450 nm-emitting blue LED chips and green SiCDs, since green SiCDs was used to convert blue light to green light. The luminous efficiency of green LEDs can reach 60.96 lm/W. The as-prepared polymerizable SiCDs are hopeful to provide new opportunity to simplify the preparation process and improve optical performances of green LEDs.
