FIG. 1.

Peak-normalized PL spectra of a ZnTe:O sample exposed to different hydrogen doses, . The exciting photon energy is ( laser). OC indicates a band due to O clusters. Normalization factors are given. Inset: PL spectra of a ZnTe:O sample before and after exposure to . The exciting photon energy is equal to (He–Ne laser), and it allows observing the O–O pair recombination band at and its passivation due to H irradiation.

FIG. 2.

Variation of the free exciton (FE) peak energy (full circles) with increasing H dose, . The FE peak position calculated on the basis of strain considerations alone [see Eq. (2)] is also shown for each hydrogen dose (empty diamonds; the dotted line is a guide for the eyes). Inset: PL spectra in the energy gap region for different H doses. Normalization factors are given.

FIG. 3.

Energy difference between the two components ( and ) of the zero-phonon line of the single O band in ZnTe:O with increasing hydrogen dose. The dotted line is a guide for the eyes. Inset: Peak-normalized PL of the zero-phonon line of the single O band before and after exposure to a H dose of (dotted lines are a guide for the eyes). Normalization factors are given.
