A summary of the article is shown below:
Efficient white light emission (WLE) using a combination of organic fluorophores requires careful modulation of their distance and orientation. We exploited the secondary inner filter effect (sIFE) between a multi-responsive 2-(1-pyrenyl)benzimidazole (PyBIM) and perylene-monoimide (PMI) secondary emitter to obtain pure WLE (CIE coordinates 0.33, 0.33) with an unsurpassed efficiency of 70 ± 3% under ambient conditions in highly diluted conditions. The sIFE based approach allows extremely efficient WLE using simple fluorophores that are spatially separated.
