摘要
Owing to the unique 4 f -5 d transition, Eu 2+ is one of the most commonly used activators in luminescent materials for phosphor-converted light-emitting diodes ( pc -LEDs), and Eu 2+ -doped phosphors exhibit outstanding luminescence properties, including multi-color emission, adjustable bandwidth, excellent thermal stability as well as high luminescence efficiency. These attributes motivate scientists to find Eu 2+ doped phosphors that can practically meet the various LED application requirements. In this talk, I will summrize our recent progresses to manipulate Eu 2+ emission exhibiting red and near-infrared emissions under blue light excitation. One can expect and further adopt proper structural engineering strategies to tune the Eu 2+ luminescence. Moreover, the state-of-the-art LED application including solid-state lighting and near infrared night-vision technologies will be also introduced based on these Eu 2+ doped phosphors. We hope this talk will be helpful for controlling the photoluminescence by theory-structure-property relationships and guide scientists discover the next generation of Eu 2+ doped phosphors for emerging applications.
