不同胁迫时间对延迟发光的影响

Influence of Different Treating Time on Delayed Luminescence from Leaves

用超弱发光测量仪测定了同一温度不同处理时间对绿宝石喜林芋叶片延迟发光的影响.结果表明:随处理时间的延长,延迟发光的衰减逐渐加快,延迟发光的衰减参数成下降趋势;延迟发光的最大强度也会随处理时间的延长而逐渐降低;当处理时间达到22 h时,虽然叶片已基本失去韧性,但叶片仍具有延迟发光的特性.

The influence of different treating time at the same temperatures on delayed luminescence （DL） from green emerald leaves has been investigated by BPCL. The results showed that with treating time adding, the attenuation of DL was becoming rapid, the attenuation coefficient gradually was decreasing, and the maximal intensity of delayed luminescence also changed. When the treating time continued 22 h, the leaves has basically no inflexibility but the DL can been detected all the same.
