纳米铝颗粒强氧化反应发光特性研究

Investigation on Luminescence Character of Strong Oxidation Reaction of Nano-Al Particle

设计了利用电爆炸铝丝产生纳米铝颗粒强氧化反应发光的实验装置,对比了纳米铝颗粒在氧气和氮气环境下发光能量的大小,测量了铝氧反应发光光谱,并对电爆炸铝丝产生纳米铝颗粒强氧化反应发光的物理条件进行了研究,结果表明:发光能量随腔内氧气压力的减小而增加;随铝丝直径先增加而后减少;随电容器储能的增加而增加,且电容器储能对发光现象存在一个门槛值。

The experiment setup used to implement luminescence of strong oxygen reaction of nano-A1 particle created by electrical explosion of A1 wires is designed. The luminescence energies in oxygen and nitride environment are compared and luminescence spectrometry of nano-Al＋02 reaction is measured. Research results show that the physical conditions affect the luminescence energy. The lower the oxygen pressure in the chamber is, the higher the energy is. The luminescence energy increases with A1 wire diameter decreasing in the beginning, but decreases afterwards. The lu- minescence energy increases with the storage energy of the capacitor increasing, and a threshold value exists.
