Pr3+ ions, another alternative near-infrared luminescence emitter though energy transfer from Eu2+ for NIR pc-LEDs
Source abstract
Abstract
Near-infrared (NIR) light-emitting diodes (LED) have garnered significant research attention worldwide. This research presents a novel near-infrared phosphor doped with Pr 3+ ions, exhibiting a broad NIR emission ranging from 800 to 1100 nm. Under 450 nm excitation, Li 3Cs 2Ba 2B 3P 6O 24:Pr 3+ material generates near-infrared emission bands peaking at 882 and 1038 nm. However, this material exhibits relatively lower luminous intensity. Through Eu 2+ co-doping, the NIR emission intensity of Li 3Cs 2Ba 2B 3P 6O 24:Pr 3+ is significantly enhanced due to energy transfer. Photoluminescence spectra and luminescence decay curves support the efficient energy transfer (ET) between Eu 2+ and Pr 3+, resulting in remarkable NIR luminescence. The study evaluates the temperature stability and practical application of Li 3Cs 2Ba 2B 3P 6O 24:Eu 2+, Pr 3+ in near-infrared LED applications. Consequently, Pr 3+ ions emerge as an alternative near-infrared luminescence emitter though energy transfer from Eu 2+ , offering new insights into developing NIR light sources for broadband NIR pc-LED applications.
