Emission Properties of ELD Doping with Laser Dyes
Electroluminescence(EL) which was founded by Lossew first in 1923, then powder type by Destriau in 1936, mutiinsulating structure by Russ and Kennedy in 1967, Multicolor EL by King and Tuenge in 1982, come from the light emission obtained by electrical excitation energy passing through a phosphor layer under applied high electrical field(10(6)V/cm). In this work, we introduced laser dyes to ZnS;Cu phosphor . White, yellow and blue was acquired with different kinds of phosphor. By doping laser dyes to former phosphor, red to violet may be come true. Basic structure is ITO/Phosphor /Insulator/Carbon. Silk screen method was used for fabricating ELD. Applied high electric field to ELD doping with laser dyes, Luminance was not controlled by laser dyes, not reducing luminance and any other properties. more than 100cd/m(2) was performed at 400Hz, 1.5kHz.
