内容記述 | We present optical and dielectric quantum-confinement effects for mesocrystals smaller than 30 Angstrom of BaTiO3 and SrBi2Ta2O9 in uniform mesopores of the MCM-41 molecular sieve. For BaTiO3 mesocrystals we observed a blueshift in optical absorption edge from 3.0(2) to 3.3(5) eV, and a decrease in dielectric constant maximum temperature from 130 to 55 degrees C. For SrBi2Ta2O9 mesocrystals we also observed an increase in the optical absorption edge from 2.7(0) to 4.1(8) eV, and a decrease in the dielectric constant maximum temperature from 320 to 180 degrees C. The observed optical and dielectric quantum-confinement effects generally agree with the recognized consequence of reduced size. (C) 2000 American Institute of Physics. | |||||
