The PT effect was evaluated by the setup shown in Figure
S1, where an 808 nm laser diode (LD) and a ZnSe infrared thermometer (LumaSense IMPAC, Germany), respectively, were used to illuminate samples and monitor the temperature of the sample surface in air in a range from 273 to 1173 K. Here, the 808 nm laser was selected as the irradiation source to avoid water absorption in tissues and improve the tissue-penetration depth
33 (link),34 (link). The temperature of the samples immersed in simulated body fluid (SBF) solution was measured with a digital thermometer (Kangyou, Nanjing, China). Optical absorption spectra were measured with a Perkin Elmer
Lambda 900 UV/Vis/NIR spectrophotometer in a spectral range from 200 to 3200 nm. PL spectra were recorded with a Zolix Omni λ3007 spectrometer equipped with an InGaAs photodetector and a SR830 Stanford lock-in amplifier. The fluorescence lifetimes were measured with a digital phosphor oscilloscope (
TDS3012C, Tektronix, America). The excitation spectra were measured with an Edinburgh Instrument
FLS 920 (Livingston, WL, UK) equipped with a liquid nitrogen-cooled photomultiplier (Hamamatsu
R5509-72, Hamamatsu, Japan).
