准LO声子模与强烈影响诸如氧化锌（ZnO）的材料的光子性质的特定缺陷有关。研究了ZnO在不同退火环境中的准LO声子的线型。实验结果表明，在大气中退火的ZnO样品中，该模式具有最大的向低波数的拉曼位移，这表明它具有最大的缺陷浓度，这可能与其绿色发射有关。
The quasi-LO phonon mode is related to the specific defects that strongly affect the photonic properties of materials such as zinc oxide (ZnO). The line shapes of the quasi-LO phonon of ZnO annealed in different environments have been investigated. The experimental results show that this mode has the greatest Raman shift to lower wavenumber for the ZnO annealed in ambient atmosphere, suggesting that it has the largest concentration of defects that may be related to its green emission.
