We report on optical and electrical properties for ternary α-(AlxCr1-x)2O3 (0 < x < 1) solid solutions synthesized using solid sate reaction method. Single R-3c phase was obtained for the Aluminum composition of 0 < x < 1. Optical absorption spectra for the solid solutions have showed a blue shift of ~ 1 eV in the optical gap. Two observations have been made from the optical characterization. First, Blue shift of transition level with the Al substitution, which is related to decrease in the Cr and O bond lengths, has been confirmed by EXAFS measurements. Second, enhancement of mixing in the d and p levels, which is responsible for p-type conduction in wide band gap semiconductors, has been verified by enhancement in the electrical conductivity. These results suggests that ternary α-(AlxCr1-x)2O3(0 < x < 1) can be useful in the field of UV transparent electronics and UV photodetectors.
