- Abstract
- We developed tandem-structured blue and yellow OLEDs optimized for optogenetics, achieving peak optical power densities of ~3.1 mW/mm² and ~3.8 mW/mm², respectively. The emission spectra were matched to the activation spectra of opsins like ChR2 and Arch, enabling effective neuronal activation and inhibition. With a custom-made 64-channel MEA, we demonstrated precise temporal correlations between OLED stimulation and neuronal responses. These results establish OLEDs as promising light sources for optogenetic applications.
