Fig. 15.From: Carbon Dots as New Generation Materials for Nanothermometer: Reviewa PL spectra (excitation wavelength, 400 nm) of N-CDs (black trace) and r-N-CDs (red trace). The inset shows I/I0−T of reduced N-CDs. b PL spectra (excitation wavelength, 400 nm) of N-CDs dispersed in C2H5OH at various temperatures. c A schematic mechanism for the temperature-dependent fluorescence intensity of N-CDs.
