Spectroscopic properties and excited-state absorption (ESA) of Ti3+ doped Al21O3 were investigated in detail. Absorption spectrum was carried in the range of 200-800 nm by UV-Vis NIR spectrometer, and the emission spectra in the range 200–900 nm was recorded by a Perkin Elmer LS 55 luminescence Spectrometer. The excitation spectra of these emissions were measured and interpreted using a band model for the Ti: Al2O3 system.
