Nanocomposite powders between zinc sulfide and gallium phosphide were synthesized. Monodisperse, submicrometer, spherical, and porous clusters of ZnS nanocrystallites were used a host material, into which a solution containing a phosphinogallane, [(t-Bu)[sub 2]GaPR[sub 2]][sub 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 temperature as low as 600 C, the composite powders maintain their integrity up to 800 C.
