Spectroscopic study of transparent forsterite nanocrystalline glass–ceramics doped with chromium

Abstract

We present a spectroscopic study of transparent forsterite nanocrystalline glass–ceramic doped with chromium, a promising active medium for near-infrared fiber-optic applications. Absorption, emission, excited-state absorption spectra, and continuous function decay analysis of luminescence decay reveal the presence of Cr3+ and Cr4+ centers in both glass and crystal phases. The optical behavior of Cr3+ and Cr4+ centers is discussed and compared with that in bulk forsterite crystals.
