Luminescence of crystals ZnSe <Al>:Gd
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2018, Vol 21, Issue 1
Abstract
It has been experimentally shown that the luminescence spectra of ZnSe <Al> crystals doped with Gd from the vapor phase contain two mutually compatible luminescence bands. It is established that the low-energy G-band is due to recombination with association of complexes and , and the boundary B-band is the result of annihilation of excitons and interband transitions.

Variational approach to the calculation of the lowest Wannier exciton state in wide type-II single semiconductor quantum wells
The possibility to change the spatial character of the Wannier exciton ground state in a wide single type-II semiconductor quantum well has been studied variationally. A heterostructure with the central layer forming a p...
Local vibrational density of states in disordered graphene
Local vibrational density of states for disordered graphene has been calculated via Green’s functions method. Disordered material has been modeled with Bethe lattice. Density of states does not include particularities sp...
Nature and kinetics of paramagnetic defects induced by beta-irradiation of chitosan
A set of chitosan samples irradiated by electrons with various doses were studied using the EPR method. Two kinds of paramagnetic defects PC1 and PC2 initiated by this irradiation due to the breakage of bonds in position...
Influence of field dependent form of collision integral on kinetic coefficients
The kinetic equation is turned out in the form that contains collision integral obviously dependent on the value of external electric and magnetic fields. The correspondent calculation of kinetic coefficients shows that...
Possible method for evaluation of virus, bacteria and yeasts infectivity by optical measurements
The possible method for evaluation of virus, bacteria and yeasts infectivity based on study of their absorption spectra has been proposed. The decrease in the samples infectivity was caused by adding the CeO2 nanoparticl...
