Time-Resolved Quantum Emission Spectrogram.The horizontal axis represents time (seconds), while the vertical axis corresponds to emission wavelength (nm). The color scale indicates emission intensity, with red representing the highest intensity and blue representing the lowest. The observed fluctuations reflect the dynamic spectral shifts of quantum emitters in monolayer WS2, influenced by local charge and strain effects.
