电致化学发光（ECL）是一种由电化学氧化还原反应引起的发光现象，在轻质、柔性发光器件方面具有潜在的应用前景。在此之前，利用含有橙子电化学发光材料Ru（bpy）3 2+的DNA修饰电极，在交流电压下成功地实现了< 100 μs的超快电化学发光响应。此外，我们还将蓝色发光的9，10-二苯基蒽（DPA）引入到由DNA/Ru（bpy）3 2+杂化膜电极组成的ECL器件中。结果表明，在DNA/Ru（bpy）32+杂化膜中，由于电化学上转换的作用，蓝色电致发光的驱动电压显著降低，响应速度超快.在这项研究中，我们研究了从DNA/Ru（bpy）3 2+-DPA器件的上转换ECL的寿命和效率，以提高器件的性能。结果表明，DNA/Ru（bpy）32+杂化膜显著提高了DPA蓝色电致发光的耐久性，DNA/Ru（bpy）32 +-DPA器件的上转换电致发光效率约为100%。百分之零点二
Electrochemiluminescence (ECL), a light-emitting phenomenon induced by electrochemical redox reactions, has potential applications in lightweight and flexible light-emitting devices. Previously, an ultrafast ECL response of< 100 μs was successfully achieved under application of alternating current voltage by using a DNA-modified electrode including Ru (bpy) 3 2+, an orange ECL material. Furthermore, we introduced blue-luminescent 9, 10-diphenylanthracene (DPA) into an ECL device consisting of DNA/Ru (bpy) 3 2+ hybrid film electrodes. Consequently, a significant decrease in the driving voltage and an ultrafast response of the blue ECL were observed for the DNA/Ru (bpy) 3 2+ hybrid film due to electrochemically triggered upconversion. In this study, we investigated the lifetime and efficiency of the upconverted ECL from the DNA/Ru (bpy) 3 2+-DPA device for improvement in the device performance. As a result, the durability of the blue ECL from DPA was significantly improved using the DNA/Ru (bpy) 3 2+ hybrid film, and the efficiency of the upconverted ECL from the DNA/Ru (bpy) 3 2+-DPA device was ca. 0.2%.
