Sunlight activated long-lasting luminescence from Ba5Si8O21: Eu(2+),Dy(3+) phosphor.
TL;DR: A novel visible long-lasting luminescence phosphor of Eu(2+)/Dy(3+) codoped Ba5Si8O21 for the first time and exhibits excellent and stable phosphorescence even in water, indicating that Ba4(Si3O8)2-like structure will be a all-weather material that can be effectively and repeatedly charged by natural daylight in all kinds of open-air environments.
Journal ArticleDOI
Temperature sensing based on the up-conversion emission of Tm3+ in a single KLuF4 microcrystal
TL;DR: In this paper, the up-conversion (UC) emission intensity of a single KLuF 4 :24%Yb 3+ /0.5%Tm 3+ particle with an average particle size of 5μm has been studied in detail.
Journal ArticleDOI
Phonon-Assisted Population Inversion in Lanthanide-Doped Upconversion Ba2 LaF7 Nanocrystals in Glass-Ceramics.
TL;DR: The effective population inversion of 2 H11/2 from 4 S3/2 state of Er3+ ions can be achieved through the annihilation of phonons and random lasing action from BLF films embedded with Yb3+ /Er3+ codoped BLF nanocrystals is demonstrated.
