本文作者研制了一种可变色发光的新型气体放电光源。定性地分析了其工作原理,并测量了器件的光谱随放电脉宽的变化特性,实验结果与理论预言相符。这为大屏幕彩色显示开辟了一条新途径。实验所采用的装置如图1所示,其中变色放电管的极问距为63mm,管颈为27mm,管 The author of this paper has developed a new type of gas discharge light source that emits light and emits light. Its working principle is qualitatively analyzed, and the variation of the spectrum of the device with the discharge pulse width is measured. The experimental results are in line with the theoretical predictions. This opens up a new way for large screen color displays. The experimental device used is shown in Figure 1, in which the discharge lamp cathode pitch is 63mm, the neck is 27mm, the tube
