英文摘要Long afterglow CaTiO3:Pr3+ceramic powders were integrated with hydrothermal TiO2nanocrystallites via "doctor-blade" and TiO2-CaTiO3:Pr3+hybrid thick films on FTO substrate were fabricated. Effects of the Pr3+doping level (0.06%, 0.3%) and the CaTiO3:Pr3+/TiO2weight ratio (0.23, 0.92) on the crystallinity, morphologies, optical transmittance and photoluminescence (PL) properties were investigated. Results showed that the crystallinity of the hybrid films originated from both TiO2nanocrystallites and CaTiO3:Pr3+ceramic particles, affected little by the integrating process. The film surface became denser and coarser due to the incorporation of CaTiO3:Pr3+micron/submicron particles, and the film thickness varied little (2.2μm). The optical transmittance of the hybrid film decreased sharply (3:Pr3+micron/submicron particles to the incident light. All the hybrid films exhibited strong PL at 613nm when excited with 332-335nm, and the film with the Ca0.997TiO3:Pr0.0033+/TiO2weight ratio of 0.23 showed the highest emission. In addition, the film exhibited a photoresponce to a broad ultraviolet excitation ranging from 288-369nm and a long emission decay time up to 30min at 613nm, possible for use in the ultraviolet detectors, solar cells and other photoelectrical devices. © 2017 World Scientific Publishing Company.
