Abstract

Based on the developed phosphate glasses P2O5–K2O–Bi2O3–Nb2O5 doped with Eu3+, the influence of AlF3 and KF on the structural and luminescent properties was investigated. For this purpose, three series of glasses containing from 5 to 15 mol% fluorides were synthesized. Two of the series included the KF additive, which was introduced in two ways - proportionally and disproportionately at the expense of the K2O share. The structural characterization (XRD, FTIR) allowed us to determine the evolution of the internal structure of the glasses caused by changes in the type and content of the introduced additives and the presence of the Eu dopant. Similarly, using DSC/DTA, the thermal properties of undoped matrices were defined. The luminescence enhancement caused by the addition of ≥10 mol% fluorides was confirmed by the obtained fluorescence spectra. The presented studies not only expand the state of knowledge about the effects of fluorides on phosphate glasses but also demonstrate the ease of obtaining materials with improved properties suitable for use as phosphor in LEDs.
添加 AlF3 和 KF 对掺杂 Eu3+ 的 P2O5 - K2O - Nb2O5 - Bi2O3 玻璃的结构和发光特性的影响
在已开发的掺杂 Eu3+ 的磷酸盐玻璃 P2O5-K2O-Bi2O3-Nb2O5 的基础上,研究了 AlF3 和 KF 对其结构和发光特性的影响。为此,合成了三个系列的玻璃,氟化物含量从 5 摩尔%到 15 摩尔%不等。其中两个系列包含 KF 添加剂,添加剂的引入有两种方式--按比例和不成比例地牺牲 K2O 的份额。通过结构表征(XRD、傅立叶变换红外光谱),我们可以确定玻璃内部结构的演变是由引入的添加剂类型和含量的变化以及 Eu 掺杂剂的存在所引起的。同样,我们还利用 DSC/DTA 确定了未掺杂基质的热特性。所获得的荧光光谱证实了添加 ≥10 mol% 的氟化物所引起的发光增强。这些研究不仅拓展了有关氟化物对磷酸盐玻璃影响的知识领域,而且证明了很容易获得性能得到改善的材料,适合用作 LED 的荧光粉。

期刊介绍: The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
