Near infrared (NIR) emission is important for several applications. Search for new hosts suitable for NIR emission continues to be a topic of interest for researchers. In this article we describe NIR emission in BiMg 2 VO 6 . Nd 3+ was used as an activator for obtaining NIR emission. Pristine and doped BiMg 2 VO 6 powders were synthesized by using solid state reaction method. BiMg 2 VO 6 crystallizes in the Pmcn space group. In the PL emission spectra, characteristic lines, with the most intense appearing at 1070 nm, were observed. The excitation also is through transitions within Nd 3+ f shell. Results on the effect of activator concentration on the luminescence intensity are also reported. The maximum intensity is observed for the composition Bi 0.095 Nd 0.05 Mg 2 VO 6 . No decrease was observed for higher concentration. Taking concentration dependence as the basis, the calculations were made which show that Nd3+ ions exchange energy among themselves when they come closer than 17.13 Å.
