摘要：用高温熔融法制备了Eu2+单掺和Dy3+-Eu3+、Tb3+-Eu3+共掺的硼铝酸盐玻璃,研究了其激发和发射光谱性能。结果表明:Eu2+单掺的玻璃在蓝光区域能够产生有效激发,并且发射峰呈现黄绿色发光,随着B2O3含量的增加,玻璃的配位场强度降低,Eu2+的发射峰发生蓝移。Dy3+-Eu3+共掺玻璃中Dy3+在451 nm处呈现最强激发峰,在其激发下Dy3+向Eu3+产生能量传递,并发出蓝、黄和红光。Tb3+-Eu3+共掺玻璃在482 nm蓝光的激发下,Tb3+向Eu3+产生能量转移,并发出绿、黄和红发光。这些发射带与蓝光发光二极管(LED)复合可产生白光。
Eu^2＋ mono- and Dy^3＋-Eu^3＋ , Tb^3＋-Eu^3＋ co-doped aluminoborate glasses were prepared by high-temperature melting method. The photoluminescence of the obtained glasses were investigated in detail. The results show that Eu^2＋ mono-doped aluminoborate glass can be effectively excited by blue light, and yellow-green emission band is observed in the emission spectrum. With the increasing of the content of B2O3, the coordination field intensity of glasses decreases and a blue shift of the Eu^2＋ emission peak occurs. The strongest excitation peak of Dy^3＋ at 451 nm is observed in the Dy^3＋-Eu^3＋ co-doped glasses. Under 451 nm excitation, Dy^3＋ and Eu^3＋ emit intense blue, yellow and red light, due to the efficient energy transfer from Tb^3＋ to Eu^3＋. Under 482 nm blue excitation, Tb^3＋-Eu^3＋ co-doped glasses emit green, yellow and red lights, and the energy transfer from Tb^3＋ to Eu^3＋ is observed. By combining these emission bands with blue LED, white light can be emitted.
