Mg含量对N掺杂MgZnO薄膜的光电性能和N掺杂行为的影响
MgZnO薄膜 N掺杂 掺杂浓度 光电性能
2014/6/10
利用射频磁控溅射技术，在相同流量的氮气、氩气混合气体条件下，在石英基片上溅射获得了不同Mg含量的N掺杂MgxZn1-xO薄膜，并研究了Mg含量对N的掺杂行为和薄膜光电性能的影响。结果显示，在N掺杂MgxZn1-xO薄膜中，随着Mg含量的增加，薄膜的电阻率增加，载流子浓度下降；X射线电子能谱中位于395eV左右的N1s峰强逐渐减弱、甚至消失；Raman光谱中与受主NO相关的位于272cm-1、642...

雾化Mg粉对烟火泵浦源性能的影响
光泵浦源 烟火药 粒径
2009/8/21
为了提高烟火泵浦激光器光泵浦源的效率，改进了泵浦源的化学配方，用雾化Mg粉部分代替原来的Al-Mg合金粉。当Mg粉与合金粉的质量比为1∶1时，药柱燃速提高为完全用Al-Mg粉时的2.1倍，光辐射强度为2.4倍；药粒的燃速提高2.4倍，光辐射强度提高2.55倍，光谱效率也有所提高。分析燃速时建立了烟火药发火后的燃烧模型。模型计算结果是：当Mg粉质量分数为50％时，燃烧时间为完全用Al-Mg粉时的2....
