Utilizing effective framework to dye energy transfer in a carbazole-based metal-organic framework for high performance white light emission tuning

Abstract

By using a carbazole derived triangular carboxylic ligand, a Zn(II) based metal-organic framework (MOF) revealing high porosity framework structure and carbazole based intense blue-light emission is obtained. The structural and photophysic characteristics of the MOF make it an ideal energy transfer platform for the accommodation and sensitization of red and green dyes for the tuning of white light emission. By simultaneously introducing red and green fluorescent dyes in the host framework and carefully controlling their contents, a high performance white-light-emitting luminophor with CIE coordinates of (0.32, 0.31), CCT of 6186 K, CRI of 91 and high quantum yield of up to 39.4% was obtained, which could be a candidate for white-light-emitting diodes (WLEDs) application.
