中文摘要 | large-sized (similar to 2 inch, 50.8 mm) gamma-ua102 single crystal has been grown by conventional czochralski (cz) method, but the crystal ha's a milky, dendriform center. the samples taken from transparent and milky parts were ground and examined by x-ray diffraction. all diffraction peaks could be indexed in gamma-lialo2. the crystal quality was characterized by x-ray rocking curve. the full-width at half-maximum (fwhm) values are 116.9 and 132.0 arcsec for transparent and milky parts, respectively. the vapor transport equilibrium (vte) technique was introduced to modify the crystal quality. after 1000 degrees c/48 h, 1100 degrees c/48 h, 1200 degrees c/48 h vte processes, the fwhm values dropped to 44.2 and 55.2 arcsec for transparent and milky part, respectively. the optical transmission of transparent part was greatly enhanced from 85% to 90%, and transmission of milky part from 75% to 80% in the range of 190 similar to 1900 nm at room temperature. when the vte temperature was raised to 1300 degrees c, the sample cracked and fwhm values of transparent and milky parts were increased to 55.2 and 80.9 arcsec, respectively. by combining cz technique with vte technique, large-sized and high quality gamma-lialo2 crystal can be obtained. |
