Abstract
This paper describes a new method for evaluating the mass contents of rare- earth elements used as dopants in LiNbO3 single crystals with respect to Nb . The method is based on the technique of total-reflection X-ray fluorescen ce (TXRF). The method presented does not require chemical manipulation of t he samples and is rapid (30 min sample preparation and 10 min analysis), pr ecise (between 2 and 8% of variation coefficient) and simple.
