Abstract:
Laser ablation inductively coupled plasma mass spectrometry ( LA_ICP_MS ) was applied for the determination of doping element chromium( Cr) content and distribution in Cr∶ZnSe crystals. Several different Cr∶ZnSe crystals were prepared by diffusion method as reference material to solve the problem of accurate quantization. The homogeneity of Cr in these samples was characterized by LA_ICP_MS and the concentrations achieved by inductively coupled plasma atomic emission spectrometry ( ICP_AES ) . With signal pot and line scan sampling, the present method provided effective position and content distribution information of Cr in ZnSe crystals, achieved the in situ analysis. The correlation coefficient of Cr in calibration curve was 0. 9992 and the detection limit was 0. 08 mg/kg. It could provide effective means for the distribution statistics of doping element in different growth condition crystals.
