Photoluminescence of EuGa2Se4:Nd3+
Photoluminescence Intracentral Transitions Europium and Neodymium Ions
2013/1/30
The photoluminescence (PL) in temperature interval 77 - 300 K is investigated in Eu Ga2Se4:Nd polycrystals. It is established that broad band PL with maximum at 561nm is caused by intracentral transit...
