The 0.075wt% Fe2O3 + 0.01wt% MnO co-doped congruent lithium niobate crystal with diameter control has been obtained. The problem that the bubble included in the grown crystals has been solved by using inner crucible during the crystal growth. On the other hand, the photorefractive property of the grown crystals was measured. The refractive efficiency was about 26%, and the recording time was about 1000 seconds.application/pdf51862 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所區熔式提拉法鈮酸鋰晶體生長zone-leveling Czochralski methodlithium niobatecrystal growthreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9345/1/912215E002016.pdf
