摘要: | Calcium indate phosphors have been prepared by solid-state reactions at 1400 degreesC. This indate matrix permits photoluminescence when doped with terbium. It was found that under ultraviolet excitation with a wavelength of 254nm the phosphors revealed yellowish green luminescence that was attributed to the transitions from D-5(4) excited state to F-7(J) multiplet ground states of Tb3+ ions. The powder X-ray diffraction, photoluminescence spectra, brightness, fluorescence decay lifetime, and chromatic characteristics of the Tb3+-activated CaIn2O4 phosphors were systematically investigated and reported.
