Abstract A potential new series of Er3+ ions doped zirconium magnesium borate (ZMB) glasses have been prepared by conventional melt quenching method. Aperiodic nature of the glasses was confirmed by X-ray diffraction analysis. SEM image shows the nonappearance of any defined shape or structure which confirms the amorphous nature. The Refractive index of the glasses increases in the value from 1.611 to 1.671 with increase of Er3+ ion concentration. The optical absorption, excitation and emission spectra of the Er3+ doped glasses were recorded from ultraviolet (UV) to visible (Vis) and near infra-red (NIR) range with different equipment’s. The oscillator strength and JO intensity parameter (Ω2, Ω4 and Ω6) were calculated from the absorption spectra. The photoluminescence spectra of the present glasses exhibit two emissions (2H11/2→4I15/2 and 4S3/2→4I15/2) bands in the visible region by exciting 491 nm and exhibit one emission (4I13/2→4I15/2) in the NIR region with the 980 nm as a excitation source. The experimental lifetime (τexp), FWHM, figure of merit ( σ P E ×τexp), gain bandwidth ( σ P E ×Δλeff) and stimulated emission cross-section ( σ P E ) values have been calculated for all the present glasses for visible and NIR emission transition. The decay spectra measured for 4I13/2→4I15/2 transition shows single exponentials for all Er3+ ion concentrations of the glasses. CIE 1931 diagram shows the exact emission colour (green) of the prepared glasses. Correlated colour temperature points show along with the block body curve line and can be used for cold lighting purposes. From the all the results, it is observed that, 1ErZMB glass is more potential candidate for green laser, optical amplifier and designing of photonic devices.

一种新型的 Er3+ 离子掺杂锆镁硼酸盐玻璃，具有非常高的量子效率，用于绿色激光和光放大器应用

摘要 采用常规熔体淬火方法制备了一系列具有潜力的新型 Er3+ 离子掺杂锆镁硼酸 (ZMB) 玻璃。X射线衍射分析证实了玻璃的非周期性。SEM 图像显示没有出现任何确定的形状或结构，这证实了无定形性质。随着Er3+离子浓度的增加，玻璃的折射率从1.611增加到1.671。用不同的设备记录了从紫外 (UV) 到可见光 (Vis) 和近红外 (NIR) 范围内的 Er3+ 掺杂玻璃的光吸收、激发和发射光谱。从吸收光谱计算振荡器强度和 JO 强度参数（Ω2、Ω4 和 Ω6）。本玻璃的光致发光光谱在可见光区通过激发 491 nm 呈现出两个发射（2H11/2→4I15/2 和 4S3/2→4I15/2）谱带，在可见光区呈现出一个发射（4I13/2→4I15/2）谱带。以 980 nm 作为激发源的 NIR 区域。已经计算了所有现有玻璃的可见光和 NIR 实验寿命 (τexp)、FWHM、品质因数 (σ PE ×τexp)、增益带宽 (σ PE ×Δλeff) 和受激发射截面 (σ PE ) 值发射过渡。对于 4I13/2→4I15/2 跃迁测量的衰变光谱显示了玻璃的所有 Er3+ 离子浓度的单指数。CIE 1931 图表显示了所制备玻璃的准确发射颜色（绿色）。相关色温点与块体曲线一起显示，可用于冷光照明。
