ABSTRACT

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 200900 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.

 

Keywords:Ti3+:Al2O3; Absorption; Charge-transfer transitions; UV-spectroscopy
