“…S3 † reveal that all CDs/PU samples possessed same groups such as N-H (3350 cm À1 ), C-N (1730 cm À1 ), C]O (1457 cm À1 ) and C-O-C (1090 cm À1 ). 32,34 The CDs are embedded in the PU matrix and the groups of carbon sources are overlapping with PU, thus it is hard to observe the difference of all CDs/PU samples in FTIR spectra. To further investigate the composition and valence state of these samples, X-ray photoelectron spectroscopy (XPS) was employed to characterize the all CDs/PU samples.…”

“…Accurately measuring the internal temperature of living organisms, as well as the gradient can promote the research on biology and biomedicine progress. [ 1–18 ] Up to now, a large number of macro‐ and micro‐sensors have been reported for the temperature sensing. [ 2–18 ] Among the utilized sensors, fluorescence‐based temperature sensors have shown great potential because they can be used as “non‐contact” tools for the dual functions of imaging and temperature sensing at molecular level synchronously.…”

[ 2–18 ] Among the utilized sensors, fluorescence‐based temperature sensors have shown great potential because they can be used as “non‐contact” tools for the dual functions of imaging and temperature sensing at molecular level synchronously. [ 5–18 ] For the last few decades, a series of fluorescent nanomaterials, such as semiconductor quantum dots, organic dyes, fluorescent polymers, and metal nanoclusters (NCs) have been developed as typical fluorescence‐based sensors for temperature detection.…”

“…[16][17][18] The groups of Yang [19] and Maser [20] also confirmed the crosslinkinge nhanced emission (CEE) effect that the hydrogen-bond-mediated supramolecular interactions from the FSGs controla nd facilitate the photoluminescence of PDs. Different types or degrees of carbonizedc ore and distinct interactions of FSG could induce unprecedented spatial organization, folding, and self-assembly, [21] changing the surfaces tate, core, and size of PDs, whicha re suspected of contributing to the photoluminescent tunability [22,23] including improvement in QY and shift in emission wavelength. [24,25] Moreover,t here are also reports [22,26] of regulating the emission wavelength by controlling the particle size [5,27] of PDs.…”
