Abstract:	Atomic layer deposition (ALD) was used to deposit platinum (Pt) shell in 0, 50, 100, and 150 cycles on thermally evaporated vanadium pentoxide (V2O5) nanostructures (NSs) with a [1 1 0] growth direction forming V2O5@Pt core-shell nanostructures (CSNSs). The optical properties that were obtained from the photoluminescence spectra showed that emission at 466 nm increased and that at 520-580 nm decreased as the number of ALD cycles of deposition of the N shell increased, owing to the localized surface plasmon resonance (LSPR) and the lowering of contact resistance at the interface between the V2O5 core and N shell.
