This work has focused on further investigations of low-pressure discharges with mercury remaining the medium of interest. It has been shown in previous work that the near-UV emissions of mercury under the pulsed operation of low-pressure mercury-argon discharges can be significantly enhanced at the expense of the resonant UV emissions at 254 nm, The ratio of intensities of 254 to 365 nm can be increased by as much as a factor of 30. It has also been shown that the reason for this enhancement is the radiation emitted between the pulses when no field is applied across the electrodes, which accounts for most of the near-UV radiation emitted at 365 nm and it has been suggested that this enhanced line can be used for phosphor excitation thus minimizing the Stake's losses and increasing efficiency of the source by as much as 44%[1,2],
