Encapsulating Rhodamine-6g in a New Anionic In-Based Metal-Organic Framework to Realize Pure White Light Emission

Herein, we report a new blue emission metal-organic framework (MOF) (In-BCTC) with high porosity and internal quantum yield (IQY) at 6.97% based on the ligand [9,9'-bicarbazole]-3,3',6,6'-tetracarboxylic acid (H4BCTC) by solvothermal method. When encapsulating trace amounts (0.003 wt%) of an orange-emitting dye Rhodamine 6G (Rho6G), there obtains bright pure white light emitting material Rho6G@In-BCTC with an ideal CIE coordinate of (0.33, 0.33) and increases its IQY up to 23.65%, with the moderate correlated color temperature (CCT: 5566K). It is an interesting development in a MOF-based white-light-emitting phosphors.
