PHOTOLUMINESCENCE OF A FINE-GRAINED POLYCRYSTALLINE CdTe FILM IN THE n-CdS / p-CdTe HETEROSTRUCTURE
Rear illumination of photoresistive layer CdS in the field of intrinsic absorption with intensity Lпс ≈ 5.102 lx almost completely destroys - and connected with it B - D - luminescence bands. Instead of them flare up an asymmetric doublet line of polaritons radiation with longitudinal excitons frequency () and a wide line small donor-acceptor pairs () on the frequency, which maximum intensity on two order below intensity of the A-line.
