玻璃陶瓷白光LED 光致发光能量传递 glass-ceramics white light emitting diodes photoluminescence energy transfer

摘要

为获得单一基质的白光发射材料, 采用熔融析晶法制备了Tm3+/Tb3+/Eu3+掺杂的硼酸盐玻璃陶瓷。采用XRD、TEM、紫外-可见分光光度计和荧光分光光度计对样品的结构、光谱特性和发光性能进行表征。实验结果表明：玻璃经(500 ℃+2 h)+(550 ℃+2 h)热处理后析出单一晶相BaAlBO3F2。在363 nm激发下, 单掺Tm3+、Tb3+、Eu3+的样品分别发出蓝光、绿光、红光。与玻璃样品相比, 玻璃陶瓷样品的发光强度明显增加。通过改变Eu3+离子浓度,玻璃陶瓷样品的色坐标由(0.291 8, 0.331 1)变化为(0.388 1, 0.338 2)。当Tm3+、Tb3+、Eu3+的浓度分别为0.4%、0.8%和0.2%时, 玻璃陶瓷样品的色坐标(0.333 9, 0.335 7)和色温(5 427.92 K)与标准白光(0.333 3, 0.333 3; 5 454.12 K)极为接近。荧光光谱和荧光衰减结果证实, 样品中存在Tm3+→Eu3+和Tb3+→Eu3+的能量传递。制备的玻璃陶瓷材料有望用于白光LED及其他光学显示器件。

Abstract

In order to obtain a single matrix white light emitting material, the Tm3+/Tb3+/Eu3+ doped borate glass ceramics were prepared by melting and crystallization method. The microstructure, spectroscopic characterizations and luminescence properties of the samples were characterized by X-ray diffraction diffractometer(XRD) and transmission electron microscope(TEM), ultraviolet-visible light detector and fluorescent spectrometer. The experimental results show that the single crystalline phase BaAlBO3F2 is precipitated after heat treatment of (500 ℃+2 h)+(550 ℃+2 h). Under 363 nm excitation, the single doped Tm3+, Tb3+ and Eu3+ samples emit blue, green and red light, respectively. Enhanced emission intensities of glass ceramic are obviously observed compared to glass sample. The color coordinates of glass ceramic samples easily change from blue light (0.313 4, 0.347 7) to warm white (0.388 6, 0.337 3) by altering concentration of Eu3+. When the concentrations of Tm3+, Tb3+, Eu3+ are 0.4%, 0.8% and 0.2%, respectively, the color coordinate (0.333 9, 0.335 7) and color temperature (5 427.92 K) of glass ceramic sample are close to that of standard white light (0.333 3, 0.333 3; 5 454.12 K). The results of fluorescence spectra and decay curves demonstrate that the energy transfer of Tm3+→Eu3+ and Tb3+→Eu3+ exists. The as-prepared glass-ceramic materials are promising to be applied to white light-emitting diodes and other optical devices.
