Abstract

Quaternary oxysulfide semiconductors with a formula of MZnOS (M = Ca, Sr, or Ba) have recently attracted a lot of attention as host materials for luminescent dopant ions. Among these oxysulfides, the BaZnOS remains largely unexplored for luminescence in comparison with the CaZnOS and SrZnOS counterparts. This study describes a highly efficient and repeatable synthesis of BaZnOS microcrystals comprising a variety of lanthanide and transition metal ions. Spectroscopic investigations reveal a host-sensitized luminescence in the dopant ions that display distinct temperature dependence of emission intensity. Accordingly, a class of BaZnOS crystals doubly doped with Pr³⁺ and Mn²⁺ is further constructed, which shows a sensitive switching of luminescence color in response to temperature change. The advances in these luminescent nanomaterials offer exciting opportunities for temperature sensing (relative sensitivity of 8.58% K^-1) and electrochromism applications.
