英文摘要:
Barium phosphate glasses with high glass transition temperature, which belong to alkali-free glasses, are valuable candidates for application in high-power laser glasses. With the introduction of SiO2 content, the thermal properties, refractive index, and mechanical properties of these glasses can be improved, while the effects that silica exerts on the structure and luminous properties of the glasses are still in need of further study. Herein, the structure and the luminous properties, containing transmittance and fluorescence properties, of Nd3+-doped barium silicophosphate glasses are studied. It is notable that both the maximum values of luminous intensity and luminous decay time appear at the composition of 26.7 mol% of SiO2, a composition which also possesses the largest ultraviolet end edge redshift. The maximum percentage of bridging oxygen (BO) is also found at this composition, which is quantified by X-ray photoelectron spectroscopy (XPS). And both the luminous intensity and luminous decay time of these glasses appear in positive correlations with the number of bridging oxygen of the glass matrix. Thus, a method to improve the luminous properties of the barium phosphate glasses through changing the local chemistry state of the dopants by introducing SiO2 content is proposed. The optimized composition found in this paper would be useful throughout the wide field of optics.
