Abstract
Chromium-doped CaMgSi2O6 ([Formula: see text]: CMS) fluorescent ceramics with various concentrations were fabricated using solid-state reaction technique. All the samples were sintered at 1250[Formula: see text]C for 3 h. Analysis of microstructure of the Cr[Formula: see text]: CMS ceramics shows homogeneous structure with grain size distributions between 0.86 nm and 2.26 nm. Luminescent spectra of the ceramics show two emission peaks, a strong peak at 872 nm and a weak peak at 960 nm because of [Formula: see text] transition of the Cr[Formula: see text] ions. Intensity of the emission peaks increases with Cr[Formula: see text] concentration, reaches maximum with 0.1 at.% Cr[Formula: see text], then decreases with higher Cr[Formula: see text] concentration. Owing to the differences in crystal field strength, the luminescent properties of the Cr[Formula: see text]: CMS fluorescent ceramics and powder are quite different.
