We present a preliminary study concerning the luminescence properties of Eu3+-doped langasite (La3Ga5SiO14 - LGS), langatate (La3Ga5.5Ta0.5O14 - LGT) and langanite (La3Ga5.5Nb0.5O14 - LGN) crystals. The luminescence, reflectance and excitation spectra are used to compare the fluorescence efficiency and determine the most efficient excitation wavelengths.

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.
