Abstract

In this communication, we report a new kind of trichromatic white light emitting Li2SiO3 (LMS): xTb3+, yEu3+, zMn4+ phosphors which were prepared by solid-state reaction method. Powder X-ray crystallographic structural analysis indicates that the sample has an orthorhombic crystal structure with the Cmc21 space group. The photoluminescence excitation and emission spectra of the LMS: 0.04Tb3+, 0.04Eu3+, zMn4+ phosphors were clearly monitored. The emission of three main colours, green, orange-red and rich red, was obtained from Tb3+, Eu3+, and Mn4+, respectively. Energy was transferred from Tb3+ → Eu3+ → Mn4+ ions, as the interactions of electric quadrupole–quadrupole (q-q) with the efficiencies of 76.6%, which resulted in the enhancement of luminescence intensity. In addition, average life time decay was determined by using double exponential fit, yielding a value of 0.286 ms under 378 nm excitation. It is noteworthy that the LMS: 0.04Tb3+, 0.04Eu3+, zMn4+ can produce white light when the Mn4+ ratio is adjusted appropriately during ultraviolet excitation. Furthermore, for the phosphors as made, the temperature-dependent luminescence spectra show good thermal quenching characteristics. The results suggest that the LMS: 0.04Tb3+, 0.04Eu3+, zMn4+ phosphors can be exploited in solid state lighting applications.

白光发光Li2SiO3:Tb3+、Eu3+、Mn4+荧光粉的光谱、光度特性及能量传递机理
在这篇通讯中,我们报告了一种新型的三基色白光发光 Li2SiO3(LMS):xTb3+、yEu3+、zMn4+ 荧光粉,该荧光粉是通过固态反应方法制备的。粉末 X 射线晶体结构分析表明,该样品具有 Cmc21 空间群的正方晶体结构。LMS:0.04Tb3+、0.04Eu3+ 和 zMn4+ 磷光体的光致发光激发和发射光谱。Tb3+ 、Eu3+ 和 Mn4+ 分别发出绿色、橙红色和浓红色三种主要颜色。能量从 Tb3+ → Eu3+ → Mn4+ 离子传递,形成电四极-四极(q-q)相互作用,效率高达 76.6%,从而增强了发光强度。此外,利用双指数拟合法确定了平均寿命衰减,在 378 纳米激发条件下的衰减值为 0.286 毫秒。值得注意的是,LMS:0.04Tb3+, 0.04Eu3+, zMn4+ 在紫外线激发时,如果适当调整 Mn4+ 的比例,就能产生白光。此外,对于所制成的荧光粉,随温度变化的发光光谱显示出良好的热淬特性。结果表明,LMS:0.04Tb3+、0.04Eu3+、zMn4+ 荧光粉可用于固态照明应用。
