摘要: A one-step surfactant–ligand co-assisted solvothermal technique was proposed for the preparation of CaS-based luminescent materials with ethylenediamine as solvent, and acetylacetone, 1-dodecanethiol polyvinylpyrrolidone capping agents. The morphologies obtained particles can be adjusted from an octahedron to a hexagonal prism or cube by changing solvent volume ratios different agent(s), mean sizes crystals changed in relatively wide range tens nanometers few micrometers. growth process dynamic mechanism were discussed. series CaS:xCe3+ nanocrystals prepared small red shift emission positions observed green yellowish-green increasing Ce3+ concentration.
