CaxSr1-xTiO3: Pr3+ ceramics have been synthesized from the solid-state calination of sol-gel composed precursors through the hydrolysis and polycondensation process of tert-n-butyl titanate (Ti(OC4H9)4), whose phase composition and microstructure are characterized with XRD and SEM. The photoluminescent behaviors have been compared with the different host composition (molecular ratio of Sr, Ca). Especially these CaxSr1-xTiO3: Pr3+ ceramic samples present double-color luminescence in visible region, blue emission (450 ∼ 500 nm) and red one (centered in 611 nm) under the the excitation of 320 nm. With the content of Ca, the intensity of red emission is enhanced while it is decreased for blue emission.

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.
