用于激光照明的荧光粉@SiO2气凝胶复合发光材料的制备与发光性能研究
Preparation and luminescence performance of phosphor@SiO2 aerogel composite luminescent material for laser illumination
摘要
Abstract
The preparation of Tb3Al5O12(TAG)phosphors was fabricated by the sol-gel method.Thermal analysis data confirm that an increase in the H3BO3 molar ratio correlates with a reduction in the transition temperature of the final phase.Concurrently,scanning electron microscopy revealed that an elevated H3BO3 molar ratio results in larger phosphor particle sizes.Under the excitation wavelength of 275 nm,the emission spectrum manifests multiple peaks within the 480-650 nm range,originating from the 5d→4f transitions of Tb3+ ions.Subsequently,the phosphor@SiO2 aerogel composite luminescent material was successfully synthesized through a combination of physical doping and a supercritical drying process.This composite luminescent material exhibited a substantial increase in the internal quantum yield,reaching 63.64%compared to the standalone phosphor.Excited by a 355 nm laser source,the phosphor@SiO2 aerogel composite luminescent material demonstrated the capability for wire-free,long-distance luminescence with commendable uniformity.These findings demonstrate the potential application prospects of the phosphor@SiO2 aerogel composite luminescent material in the domain of laser emergency lighting.关键词
