发光玻璃在白光LED照明等技术领域有重要应用,研究发光玻璃可以有效提高 LED器件的发光效率。对复合钇铝石榴石(YAG∶Ce)荧光粉磷锌硼系(PZB)微晶玻璃的发光性能影响因素进行了分析研究。利用荧光光谱等表征手段,通过正交实验方法,讨论了基质玻璃成形方式、荧光粉掺入量和烧结气氛等对微晶玻璃发光性能的影响。研究表明,基质玻璃成形方式和荧光粉掺量对微晶玻璃的发光性能有较大影响：水淬法制备的基质玻璃的发光性能优于浇注法制备的基质玻璃；当荧光粉掺量为20%(质量分数)时,相对发光强度最大,而后又趋于下降；而烧结气氛对发光性能影响不大。采用正交实验法,得出微晶玻璃试样的相对发光强度范围为1081~4577,各因素对发光强度影响顺序为荧光粉掺量>基质玻璃成形方式>烧结温度>烧结气氛。

Luminescent glass was widely used in some high-tech fields such as white LED lighting,which can greatly improve the optical efficiency of LED devices.In this work,some factors influencing the luminescent properties of P2 O5-ZnO-B2 O3 (PZB)glass-ceramics doped with YAG∶Ce phosphor were studied and analysed. Using infrared spectra and orthogonal experimental method,the effects of shaping method,YAG∶Ce phosphor content and sintering atmosphere on the luminescent properties of PZB glass-ceramic were studied.The results shown that,shaping method and phosphor content had great effects on the luminescent properties.When the phosphor content reached up to 20wt%,PZB glass-ceramic has the highest luminous intensity,but when the content continued to rise,the emission intensity decreased.Sintering atmosphere did not make any sense to the luminescent properties.Contrary to sintering atmosphere,shaping method played an important role in the lu-minescent properties.The luminescent properties of matrix glass made by water-quenched method was better than that by pouring method.From the Orthogonal test,it can be seen that the emission intensity of the glass-ceramics ranged from 1 081-4 577 a.u.From high to low,some factors that influenced the emission intensity were YAG∶Ce phosphors content,shaping method,sintering temperature and the sintering atmosphere.
