With ongoing advancements in photothermal therapy, achieving efficient tumor cell eradication while minimizing damage to healthy tissues necessitates a highly effective and non-invasive real-time temperature monitoring technique for human tissues. Herein, we report near-infrared (NIR)-II optical sensing nanoprobe featuring rare-earth-doped gadolinium oxide nanocrystals (RENCs) attached the dumbbell mesoporous silica-coated gold nanorods (AuNRs). The composite presents an intense absorption NIR region, NIR-II photoluminescence (PL) increases by 97.2 102-fold compared pure RENCs upon 980 nm irradiation. localized electric field generated through surface plasmon resonance effects of AuNRs demonstrated dumbbell-shaped distribution that aligns with structure nanoprobes, maximizing PL enhancement RENCs. Moreover, emissions are changed rising temperature, exceptional relative sensitivity 7.25% K
