Abstract: | A tunable color thin-film electroluminescent (EL) device having a stacked structure of ZnS:Tb, F/ZnS:Mn with red and green colored filters was developed. The obtained red and green emissions have high enough luminance to be considered as a practical tunable color display panel, though the color tone of the green emission approaches yellow-green. It was confirmed that varying the color between red and green can be easily done by changing the filters and applied voltage. This device should be useful for a wide variety of applications in such fields as active information display systems |
