Multichip LED packages whose advantageous in reduced material cost,good thermal dissipation and high luminous efficacy has arose excessive attention in recent development.The multichip package is the
Besides the increasing use of LEDs for various application,there are different reliability issues for LED systems.Specially high temperature in high power LED packages causes problems such as change i
LED-based lighting is becoming increasingly popular in recent year,but LED development specially for lighting application now seems unavoidable.The various benefits of LEDs and the continuous increase
Flip-chip (FC) light emitting diodes (LED) have been gaining repaid increasing attention in current LED industrial for its better thermal performance and light extraction efficiency.For an FC-LED,its
Surface plasmons (SPs) have received much attention in LEDs,since a large enhancement of photoluminescence (PL) was achieved by quantum well - surface Plasmon (QW-SP) coupling.Generally,the QWs energy
Compared with the conventional plane LEDs,the nanorods LEDs shows the poorer electrical properties.The dangling bonds at the side wall of nanorods will not only lead to the serious leakage current,but
Much progress has been made in white organic light-emitting diodes (WOLEDs) for application in high resolution displays and lighting.Among the several types of solid state lighting (SSL),high efficien
