Cross-Relaxation Dynamics in a Neodymium Doped Chalcogenide Crystal

Year: 2026

Type: article

Abstract: For the first time, the investigation of the infrared photoluminescence emission (PL) and photoluminescence excitation (PLE) behavior of Nd3+-doped ZnIn2S4 crystals were studied. The observed emission peaks were attributed to radiative transitions of Nd3+ from the metastable 4F3/2 level to the lower 4I9/2, 4I11/2, and 4I13/2 levels. The influence of dopant concentration on the optical properties was examined, revealing evidence of energy transfer between neighboring Nd3+ ions. Analysis of the photoluminescence excitation spectra further confirmed that this interaction proceeds predominantly via a cross-relaxation mechanism.
