Nanocomposite powders between zinc sulfide and gallium phosphide were synthesized. Monodisperse, submicrometer, spherical, and porous clusters of ZnS nanocrystallites were used as a host material, into which a solution containing a phosphinogallane, [( t ‐Bu) 2 GaPR 2 ] x wherein R = i ‐Pr, x = 2 or R = t ‐Bu, x = 1, was impregnated. The pure ZnS powders and the composite powders obtained after flash pyrolysis at 600°C were subsequently heat‐treated at various temperatures ranging from 500° to 900°C and characterized using a variety of techniques. While pure ZnS powders undergo significant grain growth and morphology change at temperatures as low as 600°C, the composite Powders maintain their integrity up to 800°C.
