The materials doped by erbium ions are currently used for optical signal amplification or generation. Important factors influencing the luminescence properties of a lasing ion is the surounding crystal field. In this project we would like to use the ion-implantation technique followed by subsequent annealing as a useful way to influence the crystal field of implanted ion in LiNbO₃, ZnO and special glasses.

This project continue in previous projects SPIRIT no. 117 (2011) and RITA No. 025646 (2007-2009)  .
