Narrow Bandwidth Top-Emitting OLEDs Designed for Rhodamine 6G Excitation in Biological Sensing Applications

摘要: Organic light emitting diodes (OLED) are promising candidates offering in optical sensor applications to detect different gas compositions and excitable marker groups chemical biological processes. They enable attractive solutions for monitoring the phase composition of e.g., dissolved molecular oxygen (O2) species bio reactors or excitation fluorescent markers. In this work, we investigate OLED devices biomedical excite dye rhodamine 6G (R6G). The built top emission geometry comprising a distributed Bragg reflector (DBR) acting as mirror. is optimized provide very narrow characteristic R6G at 530 nm wavelength enabling possibility minimize crosstalk between electroluminescence fluorescence R6G. DBR includes thin film encapsulation enables narrowing spectral band depending on number pairs. comparison simulation data experimental results exhibits good agreement proves process stability.
