用于全光谱照明的高效蓝色荧光粉Sr3B2O6:Bi3+发光性能
Luminescent Properties of High-efficiency Blue Phosphor Sr3B2O6:Bi3+for Full-spectrum Lighting
摘要
Abstract
The full-spectrum lighting technology aims to address the deficiencies of existing white light-emitting di-odes(LEDs),such as high correlated color temperature and insufficient color rendering index.The development of low-cost,efficient and stable non-rare-earth blue phosphors that can be excited by the near-ultraviolet has been an important research topic.In this study,a series of Sr3B2O6:Bi3+blue phosphors were successfully synthesized through the high-temperature solid-phase method.The experimental results show that when the optimal doping con-centration of Bi3+is 0.02％,this material exhibits blue light emission characteristics under the excitation of near-ul-traviolet light at 365 nm.Its emission peak is located at 450 nm,and the full width at half maximum is 69.4 nm.The quantum yield of the blue phosphors is 42.6％,and the emission intensity at 423 K can be maintained at 80.29％at room temperature,showing excellent thermal stability.Based on the encapsulation of commercial green phosphor(Ba,Sr)2SiO4:Eu2+and nitride red phosphor CaAlSiN3:Eu2+,a full-spectrum white LED device was pre-pared.Under a driving current of 20 mA,it exhibits low correlated color temperature(CCT=5 684 K)and high color rendering index(Ra=92.9).The research shows that this blue phosphor has significant application potential in full-spectrum lighting technology and provides a solid material foundation for the development of related technologies.关键词
