Series of green CaAl2O4:Tb3+ phosphors were first prepared by the Self-Propagating Combustion Synthesis (SPCS) methods. The unit cell of CaAl2O4:Tb3+ was confirmed monoclinic system with a space group P21/n by XRD analysis. Lattice constant refinement was a = 8.6831Å，b = 8.0728 Å，c = 15.1890 Å，β = 90.1647°, Z = 12. The completely precise peaks were observed in surprise from excitation and emission spectra. Rare excitation absorption of Tb3+ coming from 4f8→4f75d1 appeared in excitation spectra at 220-320nm. Emission spectra indicated that emission peaks were attributed to 5D4→7FJ (J = 6, 5, 4, 3, 2, 1, 0) at 500nm-700nm and 5D3→7FJ at 380nm-500nm. Vibration feature of products were investigated by FT-IR spectra. SEM revealed products had smooth surface, the better crystallization..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
