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. 在10K温度下的吸收光谱中观测到位于632.1nm波长处的R2色心的零声子(ZP)线,并在不同温度下对零声子(ZP)线的光谱特性和热稳定性进行了研究。
Zero Phonon(ZP) Transitions and Chemical Shifts of NaCl Crystals Implanted with Xe Ions 氙离子注入氯化钠晶体零声子(ZP)跃迁和化学位移
With temperature reduced, while the intensity of J-peak, the zero phonon line increased, anomalous enhancement of the phonon sideband was observed. 随着温度下降零声子(ZP)线J峰强度的增大,观察到声子伴带的异常加强。
