Actively controllable photoluminescence is potent for a wide variety of applications from biosensing and imaging to optoelectronic components. Traditionally, methods to achieve active emission control are limited due to complex fabrication processes or irreversible tuning. Here, we demonstrate active emission tuning, achieved by changing the ambient humidity in a fluorescent dye-containing hydrogel integrated into a metal–insulator–metal (MIM) system. Altering the overlapping region of the MIM cavity resonance and the absorption and emission spectra of the dye used is the underlying principle to achieving tunability of the emission. We first verify this by passive tuning of cavity resonance and further experimentally demonstrate active tuning in both air and aqueous environments. The proposed approach is reversible, easy to integrate, and spectrally scalable, thus providing opportunities for developing tunable photonic devices.

掺有染料的金属-水凝胶-金属腔中的湿度控制可调发射

主动可控的光致发光对于从生物传感和成像到光电元件的各种应用非常有效。传统上,由于复杂的制造过程或不可逆的调谐,实现主动发射控制的方法受到限制。在这里,我们展示了主动发射调谐,这是通过改变集成到金属-绝缘体-金属 (MIM) 系统中的含荧光染料的水凝胶中的环境湿度来实现的。改变 MIM 腔共振的重叠区域以及所用染料的吸收和发射光谱是实现发射可调性的基本原理。我们首先通过腔共振的被动调谐来验证这一点,并进一步通过实验证明在空气和水环境中的主动调谐。所提出的方法是可逆的,易于集成,
