Nd3+ emission in the garnet structure of LiCa3ZnV3O12 phosphor

Nd3+ doped vanadate phosphors are well known, mainly for their suitability for solid-state laser applications. Garnet structures are also explored for such purposes. LiCa3ZnV3O12 is one of them. Luminescence in this host has not yet been investigated. The luminescence characteristics of LiCa3ZnV3O12:Nd3+ are reported here. Two types of emissions have been observed. The self-activated luminescence could be observed under UV excitation. The characteristic emission of Nd3+ is also observed. Apart from the f- f excitation, an efficient host sensitization of Nd3+ luminescence is observed. The LiCa3ZnV3O12:Nd3+ phosphor showed an intense Near Infrared emission at 1068nmdue to the transition of 4F(3/2) -> 4I(9/2), for 350nm excitation.

Automated summary
