Title:
MANGANESE-DOPED MAGNESIUM STANNATE LUMINESCENT MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/166661
Kind Code:
A1
Abstract:
A manganese-doped magnesium stannate luminescent material, which has a molecular formula of: Mg2-x
SnO4:Mn
x
@SnO2@My
, where @ is a coating, where Mg2-x
SnO4:Mn
x
is an outer shell layer, where SnO2 is an intermediate layer shell, where M is an inner core, where M is a metal nanoparticle, where M is at least one selected among Ag, Au, Pt, Pd, and Cu, where the value of x is 0 < x ≤ 0.05, where y is the molar ratio between M and Sn, and where the value of y is 0 < y ≤ 1×10-2. The manganese-doped magnesium stannate luminescent material is a core-shell structure luminescent material, has a high internal quantum efficiency, great luminescent intensity, and the advantages of great stability and great luminescent properties. A method for preparing the manganese-doped magnesium tannate luminescent material has simple processes, low equipment requirements, and no pollution, is easy to control and applicable for industrial production, and has a broad application prospect.
