在氮气介质中，压电Transformer（PT）产生的无声放电中观察到了光发射。在PT的λ模振动中观察到光发射的空间分布，并与PT表面上的电势分布进行了比较。在λ模式振动的情况下，光图案出现在PT周围的四个区域。空间发射和电势分布明显匹配，表明光发射的强度与PT周围的电场强度有关。据观察，发光图案交替周围的PT由正弦驱动电压，诱导的压电效应的弹性振动的PT表面上。发射强度的时间变化遵循PT上的感应电场。
Light emission is observed in the silent discharge that produced by a piezoelectric transformer (PT) in nitrogen. The spatial distribution of light emission is observed in the λ mode vibration of the PT and compared with the potential distribution on the PT surface. In the case of λ mode vibration, light patterns appear at four areas around the PT. The spatial emission and potential distributions match clearly, indicating that the intensity of light emission is related to the electric field intensity around the PT. It is observed that luminous patterns alternate around the PT by sinusoidal driving voltages, as induced by the piezoelectric effect of elastic vibration on the PT surface. The temporal variation of emission intensity follows the induced electric field on the PT.
