Luminescent properties of Cd-In-Te solid solutions

The composition dependences of the unit-cell parameter for CdTe-based solid solutions in the CdTe-InTe and CdTe-In4Te3 joins have been used to determine the limits of the solid solutions. Magnetic susceptibility data and the measured and X-ray densities of the solid solutions suggest that CdTe doped with In2Te2 or In4Te3 contains In+ and In3+ on the cation site. The cathodoluminescence spectra of CdTe doped with In2Te2, In4Te3, and In2Te3 have been measured, and the effect of mixed heterovalent substitution (In+ and In3+) on the luminescence behavior of CdTe has been analyzed.
