Synthesis, characterization and formation mechanism of Gd2O2S:Pr3+,Ce3+ phosphors by sealed triple-crucible method
Ln(NO3)3 · 6H2O (Ln = Gd, Pr and Ce), urea, sodium sulfite (Na2 SO3) and carbon powder were used as the starting materials. The precursor was synthesized with Ln(NO3)3 · 6H2O (Ln = Gd, Pr and Ce) solutions and urea at 95 °C for 4 h, and then the Gd2O2 S:Pr3+,Ce3+ phosphors were prepared by calcined...
