摘要

研制了一种基于Ho3+/Tm3+/Yb3+掺杂GeO2-PbO玻璃体系的白光随机激光器。通过改变激发激光波长在974和976 nm之间，可以获得跨越蓝色（~ 480 nm）、绿色（~ 547 nm）和红色（~ 660 nm）波长的发射。通过改变激发激光能量测量的发射强度光谱来评价所发射的三种颜色具有随机的激光行为。通过分析CIE 1931色度图，确认白光发射，其坐标始终落在白光区域内。据我们所知，这是第一个基于掺有稀土离子的玻璃的白色随机激光器。

White Random Laser based on a Ho3+/Tm3+/Yb3+ doped GeO2-PbO glass

A white Random Laser based on Ho³⁺/Tm³⁺/Yb³⁺ doped GeO₂-PbO glass system was developed. By varying the excitation laser wavelength between 974 and 976 nm, emissions spanning blue (∼480 nm), green (∼547 nm) and red (∼660 nm) wavelengths were obtained. The three colors emitted presented random laser behavior, evaluated by the emission intensity spectra measured by changing the excitation laser energy. White light emission was confirmed through analysis of the CIE 1931 chromaticity diagram with coordinates consistently falling within the white light region. To our knowledge, this is the first white Random Laser based on a glass doped with rare-earth ions.

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.
