(1) Transparent and electrically conductive ITO electrodesNecessary thickness of ITO film on the outer wall of lamp envelope was about 0.3 mum.(2) Kinds and pressure of enclosed gasWe enclosed Hg-Ne or Hg-Xe mixed gas in a straight tube type of 15W size fluoresent lamp and tested them. We got better results in brightness and color controlling for Hg-Xe using suitable fluorescent materials than for Hg-Ne. We got the brightness of negative glow at highest 500 [nt] for Hg-Ne, but more than 1,000 [nt] for Hg-Xe. We were able to change the color temperature widely, 2,500 [K] -6,500 [K], for Hg-Xe.(3) Fluorescent materialsWe got good results using "NP10+NP360" and "NP92-70+NP1047" for fluorescent materials on sale.(4) Wave form of high frequency voltage between outer electrodesWe got better results in the brightness using rectangular wave voltage than sine wave voltage. But its frequency, from 20 [kHz] to 80 [kHz], didn't effect to control color temperature.Finally, we were able to control well the color temperature and got 8,000 [nt] in brightness at the maximum.

(1)透明导电ITO电极灯罩外壁ITO膜所需厚度约为0.3um。(2)封闭气体的种类和压力我们将汞-Ne或汞-Xe混合气体封闭在直管式15W荧光灯中进行测试。用合适的荧光材料对HgXe进行亮度和颜色控制的效果要好于HgNe。Hg-Ne的负辉光亮度最高为500[nT]，而HgXe的负辉光亮度最高超过1,000[nT]。我们能够很大范围地改变汞-Xe的色温，2,500[K]-6,500[K]。(3)荧光材料我们用“NP10+NP360”和“NP92-70+NP1047”在市售的荧光材料上取得了很好的效果。(4)外电极之间高频电压的波形我们使用矩形波电压比正弦波电压对亮度的影响更好。但它的频率在20[kHz]到80[khz]之间对色温的控制没有影响，最终我们能够很好地控制色温，最大亮度达到8000[nT]。
