采用原位热分解法制备了非晶态氮化镓纳米颗粒，并将环三氮化氮加入到聚苯乙烯-聚（N，N-二甲基-4-乙烯苯胺）共聚物中。透射电子显微镜、能量色散x射线能谱和x射线光电子能谱表明，该复合材料由非晶态氮化镓纳米颗粒（平均直径约为40 nm）组成，分散在共聚物中。光致发光光谱显示，非晶态氮化镓纳米粒子发射蓝光，峰值在426 nm附近。(C) 1999年美国物理研究所。[s0003 - 6951(99) 02616 - 9]。
Amorphous GaN nanoparticles were synthesized by the in situ thermal decomposition of cyclotrigallazane incorporated into a polystyrene-poly(N,N-dimethyl-4-vinylaniline) copolymer. Transmission electron microscopy, energy dispersive x-ray spectrometry, and x-ray photoelectron spectroscopy show that the composite material consists of amorphous GaN nanoparticles (average diameter similar to 40 nm) well dispersed in the copolymer. The photoluminescence spectra show blue light emission from the amorphous GaN nanoparticles, peaked at similar to 426 nm. (C) 1999 American Institute of Physics. [S0003-6951(99)02616-9].
