Abstract

We developed a procedure for the high-precision determination of matrix elements of glasses of the Ga–Ge–As–Se system, including those doped with praseodymium, in the range of concentrations of gallium from 1 to 5 at %, germanium from 16 to 24 at %, arsenic from 14 to 18 at %, and selenium from 57 to 65 at %. A procedure for determining 0.05–0.5 wt % of praseodymium in these glasses by inductively coupled plasma–atomic emission spectrometry is also proposed. The expanded uncertainty (P = 0.95) of the results in determining the matrix elements ranged from 0.05 to 0.1 at %, and for praseodymium, it was from 0.002 from 0.02 wt %. A method for preparing standard solutions necessary to achieve the stated level of uncertainty of the analysis results is described. The minimum sample weight for determining matrix elements is approximately 1 mg, and for the determination of praseodymium, it is approximately 10 mg, which enables analyzing not only bulk glass samples but also fibers made of them.

电感耦合等离子体原子发射光谱法测定Ga-Ge-As-Se玻璃中的基质元素和Pra

摘要

我们开发了一种用于高精度测定Ga-Ge-As-Se系统玻璃基质元素的程序，包括掺杂do的元素，镓的浓度范围为1至5 at％，锗的浓度为16至24 at％，砷从14到18 at％，硒从57到65 at％。还提出了一种通过电感耦合等离子体-原子发射光谱法测定这些玻璃中0.05-0.5 wt％的方法。扩展不确定度（P（＝ 0.95）确定基质元素的结果范围为0.05至0.1原子％，对于m，其为0.002至0.02重量％。描述了一种制备标准溶液的方法，该标准溶液对于达到规定的分析结果不确定性水平是必需的。用于测定基质元素的最小样品重量约为1 mg，对于for的测定约为10 mg，这不仅可以分析块状玻璃样品，还可以分析由它们制成的纤维。
