Investigations of Nanoscale Defects in Crystalline and Powder ZnSe Doped With Fe for Laser Application

摘要

The theoretical and experimental analysis of the ternary system Zn-Se-Fe forrnobtaining new fundamental information on phase using X-ray analysis andrninductively coupled plasma mass-spectrometry is carried out. New experimentalrndata of isothermal annealing in the Zn-Se-Fe system at the temperaturesrn730, 814, 1073 K by X-ray studies confirms the reliability of theoreticalrnisothermal sections. The information on Fe solubility and concentrations ofrnnative point defects of atomic scale at bi- and monovariant conditions atrn1073 and 1273 K have been carried out. Taking into account the new data onrnphase equilibria, it is possible to fabricate active ZnSe:Fe~(2+) elements torncreate an effective laser operating at the temperature of 300 K with 1.52 Joulernemission energy with efficiency of ≈50% relative to the absorbed energy.
