With an increase in intensity of the excitation light, the violet emission peak increases super linearly and the UV emission increases linearly.
随着光激发强度的增加，紫光发射强度超线性增强，且稍有蓝移，而紫外光发光强度则近似线性增加。

Optical microcavity arouses great interest in condensed state physics. It can change characters of spontaneous emission, such as spectral full width at half-maximum, lightintensity at peak and so on.
