Abstract

Zinc selenide crystals doped with iron by high-temperature diffusion in zinc and argon atmospheres are studied by the two-photon confocal microscopy. The effect of the atmosphere on the spectra and spatial distribution of two-photon excited luminescence in the range from 425 to 725 nm is studied. It is shown that doping with zinc results in the absence of impurity-defect centers formed in samples doped in an inert argon atmosphere.

锌气氛对掺杂ZnSe：Fe晶体对杂质缺陷中心组成和分布的影响

摘要

通过双光子共聚焦显微镜研究了在锌和氩气氛中高温扩散掺杂铁的硒化锌晶体。研究了大气对425-725 nm范围内双光子激发发光的光谱和空间分布的影响。结果表明，锌的掺杂导致在惰性氩气气氛中掺杂的样品中不形成杂质缺陷中心。
