Enhanced and tunable white luminescence in NaGdGeO₄: Bi3+, Dy3+ phosphors featuring anomalous thermal quenching
{{output}}
A novel series of NaGdGeO₄ phosphors co-doped with Bi3+ and Dy3+ ions were successfully synthesized via a conventional high-temperature solid-state reaction method. By systematically varying the Dy3+/Bi3+ doping concentrations, the emission color under 347 nm... ...
