Spectroscopic properties of Nd3+ doped NaLa0.5Gd0.5(WO4)2 crystals

► This paper analyses spectroscopic characteristics of NaLa0.5Gd0.5(WO4)2:Nd crystals. ► The energy level scheme for NaLa0.5Gd0.5(WO4)2:Nd was derived. ► The hypersensitivity of 4I9/2→4G5/2 transition of Nd3+ in this crystal was discussed.
