Abstract
- • A novel self-luminescence of double provskite BaLaMgTaO 6 phosphor has been developed. • The luminescent property of BaLaMgTaO6 was investigated. • The origin of the luminescence in BaLaMgTaO 6 compound was study. • The investigation result provides a platform for modeling a new near-infrared phosphor. BaLaMgTaO 6 is an excellent phosphor host with very interesting properties. In this research, we have synthesized a new near-infrared emitting BaLaMgTaO 6 phosphor. Upon ultraviolet-light excitation (365 nm), the BaLaMgTaO 6 host displays a broad emission ranging from 650 to 750 nm. The as-prepared samples were characterized and analyzed with temperature-dependent and time-resolved photoluminescence (PL), as well as X-ray photoelectron spectroscopy (XPS). Through the experimental design, we determined that the luminescence observed in the BaLaMgTaO 6 compound can be attributed to the presence of multiple defects. These findings suggest that this material could serve as a promising platform for modeling new near-infrared phosphors and be utilized in the field of solid-state lighting. A table of contents entry.
