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

Author affiliations

Abstract

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