The luminescence spectrum of Eu3+ in langanite was measured and analyzed. The radiative lifetime (τrad) of the 5D0 level and the Judd-Ofelt parameters (Ω2, Ω4, Ω6) for Eu3+-doped langanite crystal were obtained from the analysis of the luminescence spectrum. The following values were obtained: τrad = 1.11 ms, Ω2=7.16×10-20 cm2, Ω4=4.75×10-20 cm2, and Ω6≈1.66×10-20 cm2..

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.
