Chalcogenide glasses have shown potential application in non-linear optics along with IR applications. In present work, effect of bismuth (Bi) addition on the extinction coefficient (k) and optical band gap (opt g E ) of (As2Se3)90Ge10 thin films has been investigated. A single transmission spectrum has been used for the determination of k and opt g E . The opt g E decreases while k increases with Bi addition. Results have been explained on the basis of change in density of states at band gap edges and localized states..

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.
