ZnSe1-xTex epilayers were grown on a GaAs (001) substrate with 0°, 3°, 10°, and 15° tilts toward [110] by molecular beam epitaxy. The energy gap was found to increase with the substrate tilt angle. In addition, a Te-bound exciton and an exciton bound to the Te cluster in the photoluminescence spectra have been identified. The threshold temperature for the observation of the Te-bound exciton in the photoluminescence spectrum of ZnSe1-xTex epilayers was found to increase with the Te concentration.
