Analytical control of the preparation of single crystal materials by inductively coupled plasma atomic emission spectrometry

The present paper shows that inductively coupled plasma atomic emission spectrometry (ICP-AES) and the Q concept, in accordance with Boumans and Vrakking [Spectrochim. Acta Part B 43 (1988) 691 can be used in the determination of a large number of dopants with different characteristics (charge and ionic radius) in the single crystals of potassium titanylphosphate [KTiOPO4], some of its structural analogues and potassium gadolinium tungstate [KGd (WO4)(2)]. The basic conclusion from the analytical data obtained in this work is that the incorporation of Me+, Me2+, Me3+, Me4+ and Me5+ ions in the crystal lattice depend on its ionic radii. The effect of the ionic charge of the dopant ions is negligible, The light on the regularities of dopant incorporation in the crystal lattice was thrown and hence on the possibilities of modifying the properties of the single crystal materials.
