Examples in Context

  1. A zero phonon line at 632.1 nm wavelength belonged to R 2 color center are observed in the absorption spectra of the NaCl crystals measured at 10 K temperature. The spectral properties and thermal stabilities of the zero phonon line are investigated at different temperatures.
  2. With temperature reduced, while the intensity of J-peak, the zero phonon line increased, anomalous enhancement of the phonon sideband was observed.
