System of localized excitons on oxygen complexes in CdS

“…The lasing mode is achieved. In accordance with [22], the lasing (lasing radiation) at the band of 493 nm is observed at free excitons interacting with the optical phonons.…”

“…The maximum of 505 nm had evident amplificationsuper-luminescence. It is confirmed by the increased emission intensity and occurrence of directivity [22]. The amplification is at levels of the defects, which are responsible for the spontaneous luminescence band of 497 nm, 6 The limit alloying by oxygen means for the theoretically homogeneous crystal the same level E C of the base and the crystal E BE − of the most LW components of the edge emission spectrum.…”

“…Based on the above-discussed results, it can be expected that the minimum thresholds of lasing and the maximum efficiency of the CdS lasers with the electron pumping at 80−300 K [22] can be achieved on the samples of cadmium sulfide with SF of the composition of the " stoichiometry region", i.e. with a less content of oxygen.…”

“…The ICL measurements were carried out with the electron beam energy 0.1−0.02 J/cm 2 , corresponding to the excitation levels (10 26 −10 27 ) cm −3 • s −1 , using a unit of the National Research Tomsk Polytechnical University. The depth of the electron beam penetration to the sample bulk was 125−200 µm, the beam diameter was 5−10 mm [20,22]. in order to establish a relation therebetween.…”
