一、低温阴极荧光技术在阴极荧光测量中,降低温度是增强发光效率和提高分辨率的关键。同时,提高荧光的收集和传输效率也是一个很重要的因素。这里介绍一种自制的4.2°K低温样品架和椭球反射镜及一些测量结果。利用波纹管和聚四氟乙烯管同轴作成的可三维移动(±10mm)的低温样品架,在流动液氦的冷却下,一两分 First, the low temperature cathodoluminescence technology In cathodoluminescence measurement, reducing the temperature is to enhance the luminous efficiency and resolution of the key. At the same time, increasing the efficiency of fluorescence collection and transmission is also a very important factor. Here is a homemade 4.2 ° K cryogenic sample holder and ellipsoidal reflector and some measurements. A three-dimensional (± 10 mm) low-temperature sample holder made coaxially with a corrugated tube and a Teflon tube cools under the flow of liquid helium,
