Excitation dependent visible and NIR photoluminescence properties of Er³⁺, Yb³⁺ co-doped NaBi(MoO₄)₂ nanomaterials.

ABSTRACT: Due to the exceptional luminescence properties of lanthanide doped nanomaterials, they have applications in various field such as sensing, photocatalysis, solar cells, bio-imaging, therapy, diagnostics, anti-counterfeiting, latent fingerprint development, optical amplifiers, solid state lighting, etc. Here, we report the excitation dependent photoluminescence properties of Yb³⁺, Er³⁺ co-doped NaBi(MoO₄)₂ nanomaterials in both the visible and NIR regions upon UV, visible and NIR excitation. These photoluminescence properties show that strong energy transfer occurs from the host to the Yb³⁺, Er³⁺ ions. These materials show major emission bands at 530, 552 (green) and 656 nm (red) in the visible region and 1000 and 1534
