Chemical reactions under autogenic pressure at elevated temperature to fabricate photo-luminescent Ga2O3nanocrystals and their coatings
Abstract
Nanocrystalline (<20 nm) gallium oxide coating on in situ formed amorphous carbon spheres is achieved by the controlled chemical reaction of gallium triacetylacetonate under autogenic pressure at elevated temperature (700 °C) in an inert atmosphere. The as-prepared nanocomposite was further heated to 500 °C for 1 h in an air atmosphere to produce neat Ga2O3
