White Light Emission: Tailorable Upconversion White Light Emission from Pr³⁺ Single‐Doped Glass Ceramics via Simultaneous Dual‐Lasers Excitation (Advanced Optical Materials 4/2018)

Abstract

As shown by Guoping Dong, Chun Jiang, Jianrong Qiu and co‐workers (article number https://doi.org/10.1002/adom.201700787), two laser beams interacting simultaneously with crystal‐like transparency glass ceramics containing nanocrystals (blue sphericities) and rare‐earth ions (red particles) can lead to bright white light, which can convey “0” and “1” codes to thousands of families via white light fiber laser communication technology and thus finds truly practical Li‐Fi telecommunication application in people's daily life.
