Luminescence measurements show that implantation of cadmium telluride with ytterbium (followed by a suitable annealing treatment) produces an ytterbium defect capable of binding an exciton. Annihilation of the exciton bound to this defect produces a sharp emission at 1.5850 eV. Preliminary studies show that the emission does not split if the crystal is subjected to uniaxial stress. The temperature dependences of these and other excitons are studied and compared with the temperature dependences obtained for Yb 3+ emissions in ytterbium‐implanted cadmium telluride.
