제목 Dye-Bridged Hybrid Materials for Robust and High Performance White Light-Emitting Diodes
초록 Novel dye-bridged hybrid materials (DBH) have been synthesized which are one-body materials of the dye and sol-gel derived oligosiloxane to overcome limitation of the thermal stability of the dye and to increase color rendering index and color temperature tunability of white light-emitting diodes (LEDs). Structure and formation of dyes and siloxane network is studied using analysis method. The CRI and color temperature of the DBH based white LED can be controlled by tuning the concentration of each dye. DBH based white LEDs show high performance and it is ensured to have long term thermal stability for solid-state lighting application.
