    A material system is proposed to generate polariton lasing at room temperature over a broad spectral range. The system developed is based on a boron-dipyrromethene fluorescent dye (BODIPY-G1) that is dispersed into a polystyrene matrix and used as the active layer of a strongly coupled microcavity. It is shown that the BODIPY-G1 exciton polaritons undergo nonlinear emission over a broad range of exciton–cavity mode detuning in the green-yellow portion of the visible spectrum, with polariton lasing achieved over a spectral range spanning 33 nm. The recorded linewidth of ≈0.1 nm corresponds to a condensate coherence lifetime of ≈1 ps. It is proposed that similar effects can be anticipated using a range of molecular dyes in the BODIPY family; a result that paves the way for tunable polariton devices over the visible and near-infrared spectral region.
