The absorption properties of α-ZnAl2S4:Co spinel type crystals grown by chemical transport reactions method are investigated. The spectra are assigned to the electronic transitions of Co2+ ions located in tetrahedral sites. It is shown that the revealed three absorption spectral components are caused by the transitions from the ground state 4A(4F) to the excited 4T1(4F), 4T1(4P) and 2A(2G) 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.
