Investigation on the growth and luminescence spectra of congruent Linbo3 crystal obtained in air atmosphere by Czochralski Method

Single crystal of Congruent LiNbO3 (CLN) was grown by the Czochralski method in an air atmosphere with ADC (Automatic Diameter Control) r.f. heating. In this study, the optimum conditions required to grow high quality CLN single crystal are described. The high quality CLN single crystal with growth...
