Abstract

The optical properties (absorption and luminescence) of Ti3+ in a P2O5 Na2O-Al2O3 glass have been studied in the temperature range 12 to 300 K. A very broad infrared emission band at 860 nm, has been observed for the first time in an inorganic glass, when excitation is performed in the Ti3+ absorption band (T2g → Eg transition in cubic field approximation). The spectroscopic characteristics of this system are compared with those of the Ti3+ as a dopant in AL2O3 single crystals.
