Abstract
The ultraviolet-C emitting praseodymium doped yttrium phosphate (YPO4:Pr3+) powder was synthesized by conventional solid-state reaction. The electroluminescence device was fabricated by simple screen-printing method using the synthesized YPO4:Pr3+ powder, especially, polyvinylidene fluoride as an insulating layer was applied on the printed YPO4:Pr3+ powder for stable performance of the electroluminescence. The electroluminescence properties were investigated under alternating current power system of 400 Hz. The device starts to emit at 350 V, which showed the ultraviolet-C emission peaking at the 233, 245, 264, 273 nm attributed to electronic transition of the Pr3+ ions. The electroluminescence intensity was increased as increasing the operating voltage and the device revealed stable performance up to 600 V due to the polyvinylidene fluoride serve as a protective layer.
