진공급냉법을 이용하여 단성분계 $Sb_2O_3$ 유리를 제조하였다. 선형굴절율은 500-1000 nm 범위내에서 측정하였으며, 굴절율은 633 nm에서 2.0이었다. 에너지갭은 3.38 eV 이었으며, 3차 비선형 광학 감수율을 THG법을 이용하여 측정하였으며 단성분계 Silica 유리보다도 20배 큰 $5.68{ imes}10^{-13}$ esu의 측정값을 얻었다.
A single component of $Sb_2O_3$ glass has been obtained by a rapid quenching method in vacuum. The linear refractive indices were measured as a function of wavelength from 500 nm to 1060 nm. The refractive index at $n_{3{omega}}$/(633 nm) was as high as 2.00. The optical band gap was estimated as 3.38 eV from the optical absorption spectrum. The third-order nonlinear optical intensity was determined by the third harmonic generation (THG) method. The $chi^{(3)}$value was as high as $5.68{ imes}10^{-13}$esu, about 20 times larger than that of $SiO_2$ glass.
