Novel dual-mode displaying material enabling both emissive/reflective representations

提出了一种具有发射和反射双重显示模式的新型显示器件（双模显示）。这种新型器件是基于电致变色反应作为反射模式，光致发光作为发射模式。引入电致变色分子和发光镧系元素（III）配合物实现双模表示。当施加偏置电压时，该装置用作电致变色装置，并且如果照射激发光，则用作发光装置。

A novel display device with dual emissive and reflective display mode (dual-mode display) was demonstrated. The novel device was based on electrochromic reaction as reflective mode and photoluminescence as emissive mode. An electrochromic molecule and an luminescent lanthanide(III) complex were introduced for achieving dual-mode representation. The device functioned as an electrochromic device when bias voltage was applied and as a light-emitting device if excitation lights are irradiated.
