摘要
用激光诱导击穿光谱(LIBS)测量了铌II谱线的斯塔克宽度和位移。实验谱线是从激光诱导等离子体的发射光谱中获得的,这些等离子体是由硼酸盐与小铌浓度融合制备的样品产生的,选择最小的自吸收。利用不同的探测延迟时间,电子密度在0.81 × 1017 cm−3到6.7 × 1017 cm−3之间,温度在10,100-16,700 K之间。确定的26个斯塔克宽度和22个斯塔克位移包括10个多胞胎和3个构型之间转换的光谱线。据我们所知,在以前的文献中只有两个Nb II Stark宽度的实验数据。
Experimental Stark widths and shifts of Nb II spectral lines
Stark widths and shifts of Nb II spectral lines have been measured by laser-induced breakdown spectroscopy (LIBS). The experimental line profiles are obtained from spectra of the emission of laser-induced plasmas generated with samples prepared by borate fusion with small niobium concentrations, selected to minimize self-absorption. Using different time delays in the detection of the emission, electron densities ranging from 0.81 × 1017 cm−3 to 6.7 × 1017 cm−3 and temperatures in the interval 10,100–16,700 K are employed in each measurement. The 26 Stark widths and 22 Stark shifts determined include spectral lines from transitions between 10 multiplets and 3 configurations. To our knowledge, only two experimental data for Nb II Stark widths were available previously in the literature.
