摘要

采用半熔化-淬冷的一步法制备了一种新型的硅酸钙绿光玻璃陶瓷

通过变化在1 550 ℃的保温时间

研究了玻璃陶瓷中沉积的微观结构对发光性质的影响。延长保温时间

玻璃陶瓷中沉积的发光晶体-Ca

SiO

∶Eu

和发光玻璃相的比例趋于减少

导致样品发射光谱红移

透明度增加。本论文同时分析了SiO

Abstract

Calcium silicate glass-ceramic phosphor with green emission was evaluated.The effect of crystals precipitation microstructure on spectral properties was investigated by changing the holding time at melting temperature. With the in crease of holding duration

the amount ratio of luminous -Ca

SiO

∶Eu

crystalline phase to glassy phase tended to be decreased

leading to a red-shift of the emission band and exhibiting more transparent of the glass-ceramic phosphor. The precipitation of SiO

crystals in priority was proposed. The broad excitation band of the green-emitting glass-ceramic phosphors covers the wavelength from 270 to 440 nm

showing the potential for the high-power phosphor-converted LED.
