| 摘 要： | 本文利用实验室研制的强流微秒脉冲空心阴极灯电电源，研究了稀土元素Ｙｂ，Ｅｕ，Ｙ，Ｓｍ空心阴极灯的发射光谱，得到了在强流微秒脉冲和直流供电下的发射光谱图，在强流微秒脉冲下，这些元素空心极灯的谱线可增强几十至１０＾４倍，考察了电源参数和发射谱线线强度的关系。

| Abstract: | The emission spectra of Yb,Eu,Y,Sm hollow cathode lamps have been investigated with a high current microsecond pulsed(HCMP)supply developed in our laboratory.Both atomic and ionic emission lines of interest of these rare earth elements are enhanced by tens to tens of thousand times in HCMP mode compared to DC mode.Effects of parameters of the supply on emission intensities are surveyed.HCMP HCLs may be used as an economic and convenient excitation source for atomic/ionic fluorescence spectrometric analysis. |
