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 and centers in both glass and crystal phases. The optical behavior of and centers is discussed and compared with that in bulk forsterite crystals.
