The effects of two rare earth oxides such as CeO 2 and Sm 2 O 3 on the phase structure and dielectric properties of BaTiO 3 ceramic were investigated.Results in
Al2O3-SiO2-TiO2-ZrO2 supported membranes were prepared by Sol-Gel method. These composite ceramic membranes are level, even and no macro crack. There exist seve
<正>Long lasting phosphorescence (LLP) and photo-stimulated long lasting phosphorescence (PSLLP) were observed in Tb~(3+)-doped strontium borosilicate glasses.T
