White Light Emission Enhancement in Sm3+-doped Lithium Aluminum Silicate Glasses by Ag Nanoparticles
摘要
Abstract
Sm3+-doped materials exhibit red and orange emissions in the visible light region,showing broad applica-tion prospects in both laser and display material fields.However,the inherent small emission and absorption cross-sections of Sm3+result in low luminous efficiency,posing challenges for achieving high-quality solid-state lighting.Here,the excellent white emission of Sm3+doped lithium aluminum silicate(LAS)glass was realized by introducing the Ag aggregates through Ag ion exchange.Under 395 nm excitation,the Ag-doped samples exhibit significant fluo-rescence enhancement with color coordinates close to the equal energy white point E(0.33,0.33)and a color ren-dering index(CRI)of 81.8.The study reveals that the surface plasmon resonance(SPR)effect of Ag nanoparticles enhances the luminescence of Sm3+,while the energy transfer mechanism between Ag+and Sm3+also promotes fluores-cence enhancement.By adjusting the concentration of AgNO3 and the exchange time,a series of high-quality full-spectrum white light emissions were obtained,indicating that the Ag ion-exchanged Sm3+-doped LAS glass has good application potential in the development of solid-state lighting devices.Moreover,variations in the excitation wave-length can effectively tune the emission color,further demonstrating the tunability and practicality of this material in optoelectronic applications.关键词
