摘要：

Luminous zinc sulphide selenide crystals (ZnS1-xSex) with an anion-gradient in the mum-range within the crystal were quantitatively investigated by LA-ICP-MS. Reference standard crystals were synthesized by chemical vapour transport reaction and characterized by mu-XRF, SEM, PIXE, RBS and solution ICP-MS. Values from several analytical methods were then combined to describe the concentration in the reference crystals. Using these crystals, calibration curves with high correlation coefficients could be obtained for laser ablation ICP-MS determination of elemental concentrations. The gradient determined afterwards in the zinc sulphide selenide sample crystals was in the order of 30 wt% in Se-content within an 800 mum distance. This shows the promising capabilities of LA-ICP-MS in the field of elemental quantification in the mum-range.
