Series of CaAl4O7:Eu3+ were firstly synthesized as high-purity luminescence ceramic powders by using Self-Propagating Combustion Synthesis (SPCS) methods. XRD showed the unit cell of CaAl4O7:Eu3+ was confirmed monoclinic system and belonged to C2/c space groups. Lattice constant refinement was a=1.2888nm, b=0.8887nm, c=0.5445nm, β=106.9264°, Z=1. Luminescence spectra analysis indicated all peaks were attributed to 5D0→7FJ (J = 0, 1, 2, 3, 4) transition at 578nm, 590nm, 616nm, 649nm and 701nm, respectively, and energy transfer coming from host to Eu3+ enhanced luminescence intensity. FT-IR spectra investigated vibration feature of the samples. SEM revealed the samples had smooth surface, the better crystallization and ~ 1 μm size.

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.
