Confirmation of resistive heating losses (RHL) and morphological changes in posAuNP@UCNPs under IR irradiation. A Schematic illustration of the experimental setup for IR irradiation of posAuNP@UCNPs and UCNP-coated posAuNP@UCNPs. B Heating generation of posAuNP@UCNPs (1:5) compared to posAuNP under conditions irradiated up to 30 min. C Graph showing the RHL generated by posAuNP@UCNPs under IR irradiation. The RHL was measured using COMSOL. D TEM images of posAuNP@UCNPs and UCNP-coated posAuNP@UCNPs under IR irradiation for different durations. Blue arrows indicate posAuNPs@UCNPs and pink arrows indicate detached posAuNPs from the UCNP cap
