英文摘要	This work demonstrates luminescence resonance energy transfer (LRET) sensors based on lanthanide-doped nanoparticles as donors (D) and gold nanoparticles as acceptors (A), combined through electrostatic interactions between the oppositely charged nanoparticles. Negatively charged lanthanide-doped nanoparticles, YVO4:Eu and LaPO4:Ce,Tb, with high luminescence quantum yield and good water-solubility, are synthesized through a polymer-assisted hydrothermal method. Positively charged polyhedral and spherical gold nanoparticles exhibit surface plasmon resonance (SPR) bands centered at 623 and 535 nm, respectively. These bands overlap well with the emission of the EU3+ and Tb3+ ions within the lanthanide nanoparticles. Herein, the gold nanoparticles are synthesized through a seed-mediated cetyltrimethylammonium bromide (CTAB)-assisted method. ne assemblies of the oppositely charged donors and acceptors are developed into LRET-based sensors exhibiting a donor quenching efficiency close to 100%.; Chemistry, Multidisciplinary; SCI(E); PubMed; 21; ARTICLE; 10; 1857-1864; 3
