Abstract
Mutually enhanced Tm3+ 1470Â nm and Dy3+ 1330Â nm near-infrared (NIR) emissions are observed in Dy3+/Tm3+ co-doped 70GeS2-10Ga2S3-20CsCl (mol%) chalcohalide glasses. With the optimized concentration of dopant ions, the NIR emission in a range from 1250 to 1550Â nm shows the largest full-width-at-half-maximum (FWHM) of ~230Â nm. The mechanism responsible for the mutually enhanced NIR emission is discussed. The present work demonstrates a promising way to realize superbroadband NIR emissions by rare-earth codoping.
