Abstract

The invention discloses a green-white fluorescent silver quantum cluster-doped fluorphosphate glass based on non-bridging oxygen coordination, which is prepared from the following components in mole percentage: 30 to 55 percent of ZnF2, 25 to 55 percent of P2O5, 5 to 10 percent of SnO2, 5 to 10 percent of In2O3 and 0.1 to 3 percent of Ag, and a two-step high-temperature founding method is adoptedfor preparation. The glass prepared by the invention has broad-spectrum high-performance fluorescence characteristic within the visible light band and good physicochemical stability, and can be produced into a sheet applied to modulate the solar spectrum to increase the energy conversion efficiency of solar cells, or can cooperate with an ultraviolet LED (light-emitting diode) chip to serve as a fluorescence conversion layer applied in white-light LED illumination.

Description

technical field [0001] The invention relates to a noble metal-doped inorganic fluorescent glass and a preparation method thereof, in particular to a green-white fluorescent silver quantum cluster doped fluorophosphate glass based on non-bridge oxygen coordination and a preparation method thereof. Background technique [0002] Noble metal quantum clusters, especially silver quantum clusters ([Ag m ] n+ ), is a new class of metal molecular luminescent materials with excellent optical, spectroscopic, catalytic and other properties. [Ag m ] n+ Quantum clusters consist of only a few to dozens of atoms (Ag 0 ) / ion (Ag + ), where the continuous energy levels of bulk metal materials are split into discrete energy levels, resulting in strong quantum effects and molecular state fluorescence, which has the advantages of wide-spectrum tunability and high fluorescence efficiency, so it can be applied to biosensing, Data storage, temperature detection, display and lighting and other...
