Abstract

In this paper, we investigate and report the effects of alkali ions A⁺ (A⁺ = Li⁺, Na⁺, K⁺) on the optical properties, bandwidth flatness (BFN), gain coefficient (G(λ)) for the near-infrared (NIR) emission spectra of Er³⁺-doped SiO₂–ZnO–La₂O₃ (SZL) zinc silicate glass. With the change in the composition of A⁺ ions in the order from not containing any A⁺ ions → Li⁺ → Na⁺ → K⁺ → containing all three A⁺ ions including Li⁺, Na⁺, and K⁺, the direct and indirect bandgap (DBG and IBG), the absorption cross-section (σ_abs(λ)), the emission cross-section (σ_ems(λ)), and the G(λ) parameters of Er³⁺-doped SZL glasses were determined to increase gradually. NIR emission intensities of Er³⁺-doped at ⁴I_13/2 → ⁴I_15/2 transition under excitations of both 808 and 980 nm LD all were significantly increased with the composition of A⁺ ions varies in order from not containing A⁺ ions → Li⁺ → Na⁺ → K⁺ → containing all three A⁺ ions. The reasons for the influence of A⁺ ions on the UC and NIR emission intensities of Er³⁺-doped in SZL glass are investigated and discussed. In addition, upconversion (UC) emission spectra of Er³⁺-doped, CIE 1931(x; y) coordinates and color region for UC emission spectra of Er³⁺-doped SZL glasses with different compositions of A⁺ ions under excitation of 980 nm laser diode (LD) are also determined.

碱离子对掺杂 Er3+ 的硅酸锌玻璃的光学特性、带宽平坦度和近红外发射光谱增益系数的影响

本文研究并报告了碱离子 A+（A+ = Li+、Na+、K+）对掺杂 Er3+ 的 SiO2-ZnO-La2O3 (SZL) 硅酸锌玻璃近红外发射光谱的光学特性、带宽平坦度 (BFN) 和增益系数 (G(λ)) 的影响。随着 A+离子组成的变化，按照不含任何 A+离子→Li+→Na+→K+→含 Li+、Na+、K+三种 A+离子的顺序，确定了掺 Er3+ 的 SZL 玻璃的直接带隙（DBG）和间接带隙（IBG）、吸收截面（σabs(λ)）、发射截面（σems(λ)）和 G(λ)参数逐渐增大。在808 nm和980 nm LD激发下，掺杂Er3+在4I13/2→4I15/2跃迁点的近红外发射强度均随A+离子组成的变化而显著增加，依次为不含A+离子→Li+→Na+→K+→含全部三种A+离子。研究并讨论了 A+离子对掺杂在 SZL 玻璃中的 Er3+ 的 UC 和近红外发射强度产生影响的原因。此外，还测定了掺杂 Er3+ 的上转换（UC）发射光谱、不同 A+ 离子组成的掺杂 Er3+ 的 SZL 玻璃在 980 nm 激光二极管（LD）激发下的 UC 发射光谱的 CIE 1931（x; y）坐标和色区。

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.
