CuCl 미립자가 분산된 비선형 광학유리의 제조와 비선형 광특성: III. CuCl 반도체 미립자의 Bimodal 분포 특성과 온도에 따른 광흡수도
윤영권, 한원택
Preparation and Nonlinear Optical Properties of CuCl-doped Nonlinear Optical Glasses : III. Bimodal Distribution of CuCl Nanocrystals and Temperature Dependent Optical Absorption Spectra
The bimodal distribution of CuCl nano-crystals precipitated in alumino-borosilicate glass matrix (30SiO2-45B2O3-7.5Al2O3-7.5Na2O-7.5CaO-2.5GeO2(mole %)) was investigated by TEM and the temperature dependent optical spectroscopy. Two types of CuCl particles with different size were observed by TEM and it was confirmed by the splitting of Z3 absorption peak at low temperature and the occurrence of deflection point in the optical spectra with temperature.
Key words: Bimodal distribution, CuCl doped glass, $Z_3$ absorption peak splitting, Temperature dependent optical spectroscopy, Phase separation of matrix glass
