Self-Filtering Narrowband Organic Photodetectors for Non-Invasive Blood-Oxygen Monitoring
Increasing demands on medical diagnostics, miniaturized spectroscopy, and optical communication raise the need for developing compact photodetectors with spectral selectivity. Narrowband photodetector stands out as a promising solution. Self-filtering narrowband organic photodetectors respectively peaked at 660 nm and 860 nm are fabricated following the exciton dissociation narrowing (EDN) strategy. A full width at half maximum (FWHM) of 83.0 nm with a peak EQE of 59% at 860 nm and 72.9 nm with a peak EQE of 59% at 660 nm are achieved. The narrow-band photodetectors show excellent stability that maintained a high specific detectivity of
${1}.{2}\times {10}^{{12}}$
Jones at 860 nm and
${7}.{6}\times {10}^{{11}}$
Jones at 660 nm after being aged in air at room temperature for 280 days. By integrating the self-filtering narrowband photodetectors peaked at 660 nm and 860 nm with red and infrared LEDs, respectively, a device for real-time non-invasive monitoring of arterial PPG signals, blood oxygen saturation, and heart rates was realized.
