Abstract

Broadband emission in a series of alkali chlorides are achieved by doping NaCl, KCl, and RbCl with Sb³⁺. These compounds show photoluminescence peaks in the visible range of 536–574 nm with long lifetimes in the microsecond range. Our findings could offer valuable insights for the development of new lead-free phosphors.
