Abstract

Novel Ca2MgWO6 phosphors doped with xEr3+ (x = 0.5, 1, 2, 3, and 4 mol%) were synthesized using the solid-state reaction method. Using XRD and FTIR analyses, successful product formation was confirmed. Subsequently, the phosphor was optimized by focusing on the characteristic emission peak at 529 nm, arising from the transition 2H11/2 → 4I15/2. The optimal concentration of Er³⁺ for the given host system was determined to be 2 mol%. Meticulous analyses revealed that the optimized phosphor possessed a direct optical band gap of 3.68 eV and the bonding parameter confirmed that the nature of bonding was ionic nature between the dopant and the host. Furthermore, phosphor also demonstrated high thermal stability up to 500 °C, excellent thermal quenching temperature of 357.43 K, and anomalous temperature-dependent emission properties. All these incredible features make the prepared phosphor a promising candidate for multifield applications like light generation, temperature sensing, etc.
