“…Argon and nitrogen mixture is good for ultraviolet emission. Ultraviolet (UV) and Vacuum Ultraviolet (VUV) radiation are important applications (Midren and Carman 2001;Wang et al, 2009b;Zhou et al, 2008;Heikkilä et al, 2009;Anandan and Ketchum, 1994). Usually the UV lamps are tube sources.…”

Flat panel ultraviolet Lamps were made of ITO glass and bonded aluminum with porous anodic alumina on the surface. The mixture of argon and nitrogen is introduced as the working gas. The UV radiation power density is tested at different optimization conditions. The results show that the lamp with about 20 W/m 2 UV radiation can be obtained when the lamp with 3 mm thick glass and 0.7 mm gas gap distance work at 5% nitrogen and 95% argon at 250 torr. The influence factors are investigated and discussed.

“…Several GW of visible radiation are produced worldwide on a continuous basis from the lamps mentioned above but the pivotal role of Hg in present technology and the nonideal form factor of existing lamps are partially responsible for sustaining the ongoing development of new illumination sources. Other considerations fuelling the effort to identify efficient, mercury-free lamps include the slow equilibration of the Hg number density in sources of large radiating area and the rapid growth of markets such as that for liquid crystal display (LCD) backlight units which require inexpensive, reliable and spatially uniform sources of broadband (white) emission [5][6][7][8].…”

Flat lamps, having radiating areas as large as 15 × 15 cm2 and comprising arrays of Al/Al2O3 microcavity plasma devices, have been fabricated and characterized in the rare gases. Sealed arrays of devices with microcavities having diamond-shaped cross-sections yield lamps with an overall thickness of ∼800 µm (of which ∼500 µm is the quartz output window) and luminance and luminous efficacy values greater than 1600 cd m−2 and 10 lm W−1, respectively, are observed in preliminary experiments in which microplasmas in a Ne/20%Xe mixture illuminate a commercial green phosphor in a transmission arrangement with the ∼10 µm thick phosphor film situated immediately above the array. Efficacy values well in excess of 20 lm W−1 are expected when the array design and microcavity-phosphor geometry are optimized. Fully flexible arrays sealed in polymeric packaging have also been demonstrated, thereby providing access to new opportunities for lighting in which lightweight arrays are mounted onto curved surfaces.
