Structural phase transition and its consequences on optical behavior of LaV${}_{1-x}$Nb${}_x$O${}_4$

Hemanshu Dua, Rishabh Shukla, R. S. Dhaka

We present the structural, electronic, vibrational, and photoluminescence properties of polycrystalline LaV${}_{1-x}$Nb${}_x$O${}_4$ ($x=$ 0--0.2) samples at room temperature. The subst…
