p band造句

• By detecting < wp = 6 > the pl spectra under low temperature , a thermal activation process could be seen . and the possible mechanism of p band formation is discussed
  通过测量zno微米柱在不同温度下的发光光谱，发现激子-激子相互碰撞产生的热激活过程，并讨论了激子激子相互作用的机理。
• In the photoluminescence ( pl ) spectra , a new emission band due to the exciton - exciton collision process ( p band ) is observed under low excitation intensity at room temperature . and some fine structures origination from the cavity modes of the fabry - p rot etalon could also be seen clearly
  在单根zno微柱（直径有25 m ）的p带发光峰上还可以观察到明显的f - p腔模式分布，通过计算得到其腔长为21 m ，同微米柱的尺寸相当。
