Constructing near-infrared-light-mediated core-shell nanostructures incorporating upconversion nanoparticles (UCNPs) and semiconductors is of great importance for potential applications in photocatalysis, nano-biomedical engineering, solar cell, etc. In this work, we have demonstrated a two-step solution process to synthesize [email protected] core-shell nanoparticles (CSN). Firstly, a layer of AA-Zn(Cd)[OH]4− composites was coated on UCNPs to form UCNPs@AA-Zn(Cd)[OH]4− composites, which has been converted to [email protected] CSN via sulfidation reaction process using thioacetamide (TAA) as the sulfur source. Moreover, the [email protected] yolk-shell nanoparticles (YSN) have been obtained from the [email protected] CSN after calcination at 400°C, which show significantly photocatalytic activity for reduction of Cr(VI) under near-infrared light. All these can be attributed to the enhanced crystallization degree, resulting in enhanced energy transfer efficiency and separation efficiency of the photogenerated electrons and holes. An alternative strategy is provided in this study for fabrication of UCNP/semiconductor composites for various applications.
