| Abstract(in English) | The vacuum-dtraviolet (VUV) excitation spectrum of Zn_2SiO_4:Mn phosphor has such a peculiar characteristic that it keeps almost same efficientry in the much higher energy region than the host absorption edge, i.e., at such a short wavelength as 147nm used for excitation of phosphors in PDP (Plasma Display panel) and rare-gas fluoresent lamps. In order to find the origin of this unusual but preferable property of this phosphor as a VUV-excited phosphor, some phosphors based on zinc oxoacid-salts (Zn_2SiO_4, ZnGa_2_4, ZnAl_2O_4) activated by Ti Cr are investigated. It is shown that the unusual property of Zn_2SiO_4:Mn phosphor is rather common to Zn-O based phosphors, indicating an efficient excitation energy transfer among Zn-O atomic groups. Some new VUV-excited phosphors are proposed for the improvement of the color gamut of PDP and rare-gas fluorescent lamps. |
