(color online) Variation of the fluorescence intensity from the emission lines of NO molecule with percentage of NO molecular gas concentration at different discharge electric current values of 10, 30, 50, 80, and 100 mA, a fixed glow discharge voltage at 30 kV in the glow discharge and 25-mbar NO gas pressure. The temperature in cavity tube is kept at 40 °C.
