Abstract
Zinc manganese silicate containing metal particles luminescent materials and preparation methods thereof are provided. The said luminescent materials are a blend of metal M nanoparticles and ZnSiO:Mn, wherein M is one of Ag, Au and Pt, 0.001≦x≦0.1, 0.00001≦y≦0.01, y is the molar ratio of M to ZnSiO:Mn. The said methods include the following steps: step, preparing silica aerogel containing metal particles; step, weighing source compound of zinc, source compound of manganese and the silica aerogel in stepat stoichiometric ratio and mixing them to form mixture; step, sintering the mixture in step, then cooling and grinding to form the said luminescent materials with higher luminescent intensity. The said methods have simple steps, easy operation, low sintering temperature and low cost.
