Abstract

Alternating current electroluminescent (ACEL) devices have attracted tremendous attention due to their significant applications in bioinspired electronics, smart wearables, and human-machine interfaces. However, it still faces limitations in real-time visual temperature sensing. Herein, a universal strategy is established to achieve real-time temperature dynamic visualization by integrating a thermochromic layer through a simple spin coating procedure. Such elaborate integration permits the device to display a wide array of luminous colors and achieve high-contrast color transitions in response to ambient temperature variations. More importantly, a quantitative relationship can be established between the temperatures and the luminous color changes. This advancement not only enhances multi-color emission capabilities but also enables the display of diverse information, marking a significant stride in the development of dynamic temperature sensing in ACEL devices.

用于实时视觉温度监测的热响应彩色可调电致发光装置

交变电流电致发光（ACEL）器件因其在生物启发电子学、智能可穿戴设备和人机界面中的重要应用而备受关注。然而，它在实时视觉温度传感方面仍然面临着局限性。在本文中，通过简单的旋涂过程集成热致变色层，建立了实现实时温度动态可视化的通用策略。这种精心设计的集成使设备能够显示多种发光颜色，并根据环境温度变化实现高对比度的颜色转换。更重要的是，可以在温度和发光颜色变化之间建立定量关系。这一进步不仅增强了多色发光能力，还能显示各种信息，标志着 ACEL 器件在动态温度传感方面取得了重大进展。
