A Emission Property of Powder EL device at 60Hz
상용주파수(60Hz)에서 후막 EL소자의 발광특성
Abstract
Electroluminescence is occurred when phosphor is located in electric field. Object of this research show powder electroluminescent device (PELD) for high brightness compared with conventional PELD. Single layer of PELD structured as follow (ITO/phosphor + dielectric/silver paste). To investigate optical properties of PELDS, EL spectrum, CIE coordinate system, Brightness of PELDs was measured. The suitable ratio between phosphor and dielectric in single layer of PELD was 7:3(phosphor: dielectric). At 200 V4OO Hz, high performance of PELD which had ratio of 7:3
