By examining factors like excitation power density and Yb\u00b3\u207a ion concentration, the team observed that high power densities triggered a shift from green to yellow luminescence in self-activated samples. In contrast, the NaBi(MoO\u2084)\u2082 crystal maintained bright green luminescence across the tested power range.<\/p>\n\n\n\n<p>These findings are significant because they clarify the EBT mechanism, which had not been thoroughly explored in prior studies. The researchers identified how EBT relates to excitation power density, Yb\u00b3\u207a concentration, and the structural order of the material. This insight offers a theoretical foundation for optimizing optical temperature measurement techniques.<\/p>\n\n\n\n<p>The study opens new avenues for designing efficient luminescent materials, with potential applications in sensors, displays, and other photonic devices.
