Growth and structure of Nd3+-doped Li3Ba2Y3(WO4)8 crystal with a disorder structure

Abstract

An Nd³⁺-doped Li₃Ba₂Y₃(WO₄)₈ crystal with dimensions up to 32 × 20 × 14 mm³ has been grown by the TSSG method. The Li₃Ba₂Y₃(WO₄)₈ crystal crystallizes in the monoclinic system with the space group C2/c. The unit cell parameters are a = 5.181(2) Å, b = 12.677(7) Å, c = 19.161(10) Å, β = 92.237(13)° and Z = 2. The Li₃Ba₂Y₃(WO₄)₈ crystal has a high structure disorder. The spectral properties of Nd³⁺-doped Li₃Ba₂Y₃(WO₄)₈ crystal exhibited broad absorption and emission bands, which are caused by the disordered structure of the Li₃Ba₂Y₃(WO₄)₈ crystal. Therefore, it may be regarded as a laser host material for diode laser pumping.
