摘要: Cross-relaxation among sensitizers is commonly regarded as deleterious in fluorescent materials, although favorable photothermal agents. Herein, we coated Prussian blue (PB) on NaNdF4 nanoparticles to fabricate core-shell nanocomplexes with new cross relaxation pathways between the ladder-like energy levels of Nd3+ ions and continuous band PB. The conversion efficiency was improved exceptionally mechanism enhanced effect investigated. In vivo photoacoustic imaging therapy demonstrated potential Moreover, concept generating cross-relaxation different materials proposed contribute design all kinds
