Broadband near-IR emission from cubic perovskite KZnF sub(3):Ni super(2+) nanocrystals embedded glass-ceramics

Transparent KF-ZnF sub(2)-SiO sub(2) glass-ceramics were prepared with the precipitation of KZnF sub(3):Ni super(2+) nanocrystals. During excitation with a wavelength of 405 nm at room temperature, a broadband near-IR emission centered at 1695 nm with the FWHM of more than 350 nm was observed, which...
