Optical Energy Gap of Ti:Al2O3 Single Crystals
Hamdan Hadi Kusuma, Zuhairi Ibrahim and Mohamad Khairi Saidin

Abstract:
The optical absorption spectra of single crystals of titanium doped sapphire (Ti:Al2O3) with two different doping concentration (0.1% wt. and 0.25% wt.) have been recorded in the UV-visible spectroscopy at room temperature. It was observed that both crystals start to show strong absorptions around 325 nm. From this spectrum attempt was made to estimate the values of energy gap and the type of transition occurs in Ti:Al2O3. From the analysis it show that the optical energy gap are 5.57 eV for 0.1% wt. Ti and 5.94 eV for 0.25 wt.% Ti and it a direct band gap transition.
