Аннотация

Pr3+ doped WO3-Gd2O3-B2O3 glasses were prepared by the melt quenching technique to study in the luminescence under different excitation. X-ray diffraction (XRD) pattern represents the dominant vitreous disordered structure. The glass with 2.0 mol% of Pr2O3 possess a massive density at 6.15 g/cm3. The luminescence spectra of Pr3+ doped glasses were recorded under the various excitation wavelengths of visible light and under the electron excitation. The streak camera was used to measure decay time. The developed glasses show tunable luminescence property, orange under 435 and 447 nm excitation, yellow under 471 and 484 nm excitation and white under the electron excitation. The photo- and catodoluminescence decay times of glasses are comparable. The optimal concentration of Pr2O3 in the glass is 0.1 mol% that performed the highest emission intensity. This glass can be considered as a new low-cost alternative for the tunable light source and the electron detection material.
