The Nd3+ and Sm3+ spectroscopic characteristics (energy levels and emission wavelengths) dependences on the host structure and composition are analyzed. These ions are interesting for visible emission: blue obtained by doubling the Nd3+ laser emission in 900 nm range and orange –red by direct pumping of Sm3+ ion. The hosts are different oxide materials: sesquioxides ceramics Y2O3, Sc2O3, garnet ceramics Y3Al5O12 – YAG and hexaaluminates Sr1-xLaxMgxAl12-xO19 – ASL single crystals. The data are discussed in terms of the nephelauxetic effect and the crystal field strengths. The role of both effects on the emission wavelengths is outlined..

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.
