Erbium doped heavy metal oxide containing glasses have prominent applications in the field of photonics. In this paper, small concentrations of erbium oxide (Er2O3 = 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) mixed bismuth borolead lithium glasses were developed by conventional melt-quenching technique. The extensive structural and optical properties of the glasses were investigated by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Optical absorption (OA) and Photoluminescence spectroscopy (PL). The bonding parameters and the oscillator strengths (Fcal and Fexp) were calculated by using absorption spectra. The J-O intensity parameters (Ω2, Ω4, and Ω6) of the present glasses have shown a trend Ω264, which gives host glass has good quality and covalence nature and also the quality factor was observed to be less than one indicating the transitions of high intensities. The prepared glasses were excited under (480 nm), exhibited green luminescence at (527 nm) (2H11/2 → 4I15/2), 547 nm (4S3/2 → 4I15/2) and red luminescence at 656 nm (4S9/2 → 4I15/2). It is found that the luminescence properties increased with increase in Er3+ ion content up to 1.5 mol% and then decreases due to luminescence quenching. Radiation properties of present network glasses were evaluated and analyzed. The obtained experimental results indicate that the present glasses can be suitable for production of potential display devices, optical amplifiers and green lasers.

用于固态激光器和光纤放大器的掺有Er 3+离子的硼酸铋铋锂玻璃的光谱研究

含的重金属氧化物玻璃在光子学领域具有重要的应用。在本文中, 通过常规的熔融淬火技术开发了低浓度的氧化(Er 2 O 3 = 0.5、1.0、1.5、2.0和2.5摩尔%)混合铋硼铅锂玻璃。通过X射线衍射(XRD),傅里叶变换红外光谱(FTIR),光吸收(OA)和光致发光光谱(PL)研究了玻璃的广泛结构和光学性质。通过使用吸收光谱计算键合参数和振荡器强度(F cal和F exp)。的JO强度参数(Ω 2,Ω 4,和Ω6本眼镜的)都表现出了趋势Ω 264,这给主机玻璃具有良好的质量和共价性,还可以观察到的质量因子为小于一个指示高强度的转换。制备的玻璃在(480 nm)激发,在(527 nm)(2 H 11/ 2  →  4 I 15/2),547 nm(4 S 3/2  →  4 I 15/2)呈现绿色发光和红色发光在656纳米(4小号9/2  →  415/2)。发现发光性质随着Er 3+离子含量的增加而增加,直至1.5mol%,然后由于发光猝灭而降低。目前的网络眼镜的辐射性能进行了评估和分析。获得的实验结果表明,本发明的眼镜可以适合于潜在的显示设备,光学放大器和绿色激光器的生产。
