| 摘 要： | 采用熔融法制备了新颖的单掺Eu3+,Au/Eu3+和Au3+/Eu3+共掺的硅酸盐玻璃,并对这些玻璃的发光特性进行了初步研究.测试了玻璃的吸收光谱、激发光谱和发射光谱.在经过还原热处理的样品中观察到了强的Au表面等离子共振吸收带,证明了体系中确实有Au的存在.结果表明由于Au3+的存在使得O2-与Au3+发生电荷迁移,电荷迁移带的强度明显增强.发光强度在电荷迁移带(CT)240nm激发下有所增强,而在共振激发(394nm)下却减弱了.Eu3+荧光衰减寿命没有明显变化.

| Abstract: | A series of silicate glasses doped with Eu3+ and codoped with Au/ Eu3+ were prepared using melted method. The UV-Vis absorption, excitation, emission and fluorescence lifetimes of these glasses were studied. That the tendency of the emission intensity of Eu3+ was opposite each other when excited by CTS (240 nm) and resonance excited (394 nm) |
