WHITE-LIGHT FLUORESCENT MATERIAL, AND MANUFACTURING METHOD AND USE THEREOF

摘要

The present disclosure discloses a fluorescent material and a manufacturing method and use thereof. The fluorescent material comprises SnO2 doped with Ag, wherein the molar ratio of Ag to SnO2 is 0.0014-0.007:1. The fluorescent material can emit fluorescent lights of two different colors which are complementary colors of each other, and the fluorescent material has a long service life. The fluorescent material is synthesized via a hydrothermal method under air atmosphere by using SnCl4.5H2O as a raw material. The method for manufacturing the fluorescent material is easy and simple, and significant economic and social benefits can be obtained when it is popularized and applied in the fields of illumination and display. The fluorescent material can be employed for manufacturing white-light fluorescent powder used in a white-light LED excitable by an ultraviolet-near ultraviolet LED diode chip.
