Notably, the emission intensity increased nearly threefold as the Gd\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    concentration rose from 0.2 to 0.8\u2009mol%. The results were examined using Judd\u2013Ofelt analysis and supported by decay kinetics, infrared spectra, ESR spectra, and DSC studies. The enhancement of luminescence was mainly attributed to reduced phonon losses associated with Ga\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    .
