Spectroscopy of low-phonon-energy Er:La

Lanthanum oxysulfide powders doped with Erbium ions were fabricated by the combustion method followed by sulfurization at 1000 °C under H2S + N2 atmosphere. X-ray diffraction confirms their single-phase nature (sp. gr. P-3m1). Raman spectroscopy reveals a maximum phonon energy of 389 cm-1. The effect of Er3+ doping level (0.5 – 7 mol%) on the visible and mid-infrared emission properties of Er:La2O2S was studied.

Abstract

Lanthanum oxysulfide powders doped with Erbium ions were fabricated by the combustion method followed by sulfurization at 1000 °C under H2S + N2 atmosphere. X-ray diffraction confirms their single-phase nature (sp. gr. P-3m1). Raman spectroscopy reveals a maximum phonon energy of 389 cm-1. The effect of Er3+ doping level (0.5 – 7 mol%) on the visible and mid-infrared emission properties of Er:La2O2S was studied.
