Alkaline-earth silicate phosphors doped with divalent europium ion (Eu2+) were synthesized by traditional solid-state reaction. The structure of the phosphors was confirmed by XRD profiles. These phosphors exhibited an intense blue emission band in the visible region originated from the 4f-5d transitions of Eu2+ ion. The effect of SiO2 concentration in this phosphor with emission intensity and band positions has been discussed. With a combination of different emission bands, the phosphors emit white color indicating as promising candidates for white light emitting diodes.

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.
