Temperature and concentration quenching of mid-IR photoluminescence in iron doped ZnSe and ZnS laser crystals

Academic Article

Abstract

  • Concentration dependences of the mid-IR kinetic of luminescence at 5E↔ 5T 2 transition in Fe:ZnSe and Fe:ZnS laser samples were studied in 14300 K temperature ranges. Radiation lifetime in Fe:ZnSe samples measured using low doped samples with iron concentration 0.1×10 18 cm -3 was estimated to be 57 μs. The magnetic susceptibility for higher doped (C Fe=38 and 112×10 18 cm -3) Fe:ZnSe samples was found to consist of a paramagnetic CurieWeiss behavior arising from the weakly interacting Fe 2 ions and a diamagnetic ZnSe contribution plus a temperature-independent, field-dependent contribution possibly arising from very small amounts of aggregated Fe. © 2011 Elsevier B.V.
