Optical Properties and Night Vision Imaging of BaMg1.072Al9.928O17:Eu Near-infrared Luminescent Materials for Tunnel Lighting
摘要
Abstract
This research,in response to the urgent demand for high-performance near-infrared(NIR)light sources in fields such as tunnel lighting,has successfully developed a BaMg1.072Al9.928O17∶Eu(BMAO∶Eu)NIR phosphor with excellent luminous efficiency and thermal stability,aiming to provide a new material solution for the construc-tion of night vision compatible intelligent lighting systems.BaMg1.072Al9.928O17(BMAO)has been synthesized by high-temperature solid-state sintering.The material exhibits a NIR emission at 780 nm with an internal quantum effi-ciency of 55.7%.The NIR emission originated from oxygen vacancy(VÖ)defects is confirmed by introducing Eu3+ions,changing the sintering atmosphere,and introducing charge compensators.The coupling mechanism of defect-induced charge imbalance,coexistence of reduced valence states,multi-band emission,and energy transfer have been demonstrated.Finally,the NIR pc-LEDs fabricated by combining BMAO∶0.03Eu with a 365 nm ultraviolet chip showed application potential in night vision lighting and biological penetration.The synthesis method of this ma-terial provides a reference for guiding the synthesis of fluorescent materials for night vision lighting.关键词
