Abstract
To find the spectral properties of AGNs in optical spectral band (around the Hb line) we constructed an Fe II template, that is covering Fe II emission from 4100 A to 5600 A. Using the new Fe II template we explored spectral properties of 302 type 1 AGNs. The most interesting results we found is the correlation of the Hb Full Width at Half Maximum (FWHM) and luminosity for a subsample of type 1 AGNs where the ratio of narrow lines indicates a significant starburst contribution.
