研究目的
Investigating the luminescent properties of Pr3+ doped PbGdB7O13 phosphor synthesized by high temperature solid state reaction and its potential applications in display, indication, or illumination.
研究成果
The Pr3+ doped PbGdB7O13 phosphor exhibits strong red emission under blue light excitation, with optimal luminescence at 2 mol% Pr3+ concentration. The CIE coordinates indicate potential applications in display and LED technologies.
研究不足
The reaction temperature cannot exceed 900 °C to avoid partial melting and impurity phases. The particle size and agglomeration may affect the luminescent properties.
1：Experimental Design and Method Selection:
The phosphor was synthesized using the traditional high temperature solid phase method.
2：Sample Selection and Data Sources:
Raw materials including PbO, H3BO3, Gd2O3, and Pr6O11 were used.
3：List of Experimental Equipment and Materials:
A Rigaku SmartLab 9 KW diffractometer, SEM (Carl Zeiss AG, Merlin Compact), and Fluorolog-3 combined time Rresolved & steady state fluorescence spectrometer were used.
4：Experimental Procedures and Operational Workflow:
The mixture was ground, placed in a platinum crucible, and sintered at 600 °C for 10 h, then at 850 °C for 40 h.
5：Data Analysis Methods:
The luminescent properties were analyzed using excitation and emission spectra.
