Optical properties of Cr 2 + : ZnSe single crystal and film

Your library or personal account may give you access

Abstract

To realize an electrically pumped compact mid-IR microlaser, the optical properties of a Cr2+:ZnSe film deposited by rf magnetron cosputtering were compared with those of a single crystal. The mid-IR room temperature photoluminescence efficiency of the film appears only twice less than the one of the single crystal under direct (1850 nm) and indirect (458 nm) excitations. The smaller Cr2+ fluorescence lifetime values of the film were attributed to the presence in the film of a large amount of chromium in a valence state different from Cr2+ and of structural defects in the ZnSe host matrix.
