In Ref. 1, estimated value of the overlap integral square , using (1), (2) and experimental results of the absorption of colloidal CdS QDs, synthesized by an aqueous synthesis in a gelatin matrix was investigated. For the hole transitions from the equidistant quantum levers: (), (), (), () (here , are the orbital and magnetic quantum numbers of an hole), to the lowest electron size – quantized level (, ), we have Display Formula
(3)where , , , . From the above expression, it follows that the main contribution in the light absorption coefficient is a cadmium sulphide QD from the hole spectral lines corresponding to quantum numbers (; ) and (; ) the transition oscillator strengths of which are dominant.1 The contribution of higher exited hole lines (; ) is negligible.
