通过原位氮化镁，再与溶胶-凝胶衍生的二氧化硅颗粒进行复分解反应，制备了氮化硅纳米晶体。通过氢氟酸蚀刻，分离出具有Si-H和N-H主导的复杂表面化学结构的高发光、独立的β - si3n4 NCs。
Silicon nitride nanocrystals (NCs) have been prepared via in situ nitridation of magnesium followed by a metathesis reaction with sol-gel derived silica particles. Highly luminescent, freestanding beta-Si3N4 NCs with complex surface chemistry dominated by Si-H and N-H moieties were isolated upon etching with hydrofluoric acid.
