Crystals were grown from vapor phase by controlled sublimation in an electric furnace and from alcoholic solution. Crystals were transparent from 2200 Å with the measurement in the range of ultraviolet and visible spectrum, and showed dodecahedral habit exhibiting a distinct {100} natural growth faces. Crystalline index of refraction at 20℃ was measured using microacope to be 1.57 at wavelength of 5893 Å. The electro-optic coefficient γ_\u003c41\u003e was found to be 0.68~1.2x 10- ^\u003c10\u003e cm/V for 5893 Å at room temperature. The applied voltage required to produce a phase difference of π, or one-half wavelength is about 63 KV for the crystal grown from alcoholic solution. The wavelength dependence of the electro-optic coefficients, the half-wave voltage, and the conditions for the crystal growth are discussed. Nonlinear susceptibility and the second harmonic coefficnt are estimated to be 0.6 Xl0-^\u003c10\u003e cm/V and the order of l0-^\u003c10\u003e cm/V, respectively.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学理工学部"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/23493"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025080X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学理工学部紀要. 理学編"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of Ryukyus.
