홈페이지논문 초록 (Abstract)
White organic light-emitting diodes (WOLEDs) are one of the most promising technologies to realize future solid-state lighting wi th high power efficiency, broad and adjustable spectral coverage, and ar ea emission for more effective and natural illumination. In this wo rk, we report a new method of tuning the correlated color temperature ( CCT) of WOLEDs via spatially controlling the degree of the microcavity e ffect in an OLED. Varying the width of thin Ag strips deposited on top of a transparent electrode leads to changes in both intensity and pha se of reflection at the anode, hence significantly altering emission s pectra of proposed WOLEDs. CCT of the implemented WOLEDs span a wide ra nge, from 3000 K to 8000 K, demonstrating that our proposed approach helps to meet the need for lighting with various CCTs. (C) 2015 Elsev ier B.V.
