Er3+ ions doped in CdS silica glasses were prepared by sol-gel route. Absorption and photoluminescence spectra of the glasses were analyzed in the light of the Judd-Ofelt theory. Spectroscopic analysis of the multiphoton processes in the glasses was carried out by monitoring the upconversion luminescence. The study reveals the potential of the present glass for the 4S3/2 → 4I15/2 and 2H11/2 → 4I15/2 Erbium lasing transitions..

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.
