Rice-like, 2D hexagonal plate-like and truncated octahedral structures YF3: Er3+/Yb3+were prepared. Morphology-dependent UC emission color, heating capabilities and thermometric sensitivity were investigated. Stable thermometric sensitivity is independent of sizes and morphologies of YF3: Er3+/Yb3+ samples. The potentiality of rice-like nano-crystals for non-contact temperature detection in sub-tissue was demonstrated by ex vivo experiments.
