“…[23] The ECL dynamic quenching mechanism can be due to diffusive collisions between the phenolic compound (quencher) and the luminophore during the lifetime of the excited state (in this study Ru(bpy) 3 2+* ), not generating ECL intensity. [24] The static quenching mechanism can be related to the formation of a ground state complex of quencher‐luminophore (phenolic compound‐Ru(bpy) 3 2+ ), which does not generate ECL intensity; nevertheless, ECL intensity can be emitted by the uncomplexed luminophores after excitation with normal excited state properties.

Phenolic compounds such as vanillic and p ‐coumaric acids are pollutants of major concern in the agro‐industrial processing, thereby their effective detection in the industrial environment is essential to reduce exposure. Herein, we present the quenching effect of these compounds on the electrochemiluminescence (ECL) of the Ru(bpy) 3 2+ /TPrA (TPrA=tri‐ n ‐propylamine) system at a disposable screen‐printed carbon electrode. Transient ECL profiles are obtained from multiple video frames following 1.2 V application by a smartphone‐based ECL sensor. A wide range of detection was achieved using the sensor with limit of detection of 0.26 μ m and 0.68 μ m for vanillic and p ‐coumaric acids, respectively. The estimated quenching constants determined that the quenching efficiency of vanillic acid is at least two‐fold that of p ‐coumaric acid under the current detection conditions. The present ECL quenching approach provided an effective method to detect phenolic compounds using a low‐cost, portable smartphone‐based ECL sensor.

Light‐emitting transistors (LETs) have attracted a significant amount of interest as multifunctional building blocks for next‐generation electronics and optoelectronic devices. However, it is challenging to obtain LETs with a high carrier mobility and uniform light‐emission because the semiconductor channel should provide both the electrical charge transport and optical light‐emission, and typical emissive semiconductors have low, imbalanced carrier mobilities. In this work, a novel device platform that adapts the electrochemiluminescence (ECL) principle in LETs, referred to as an ECL transistor (ECLT) is proposed. ECL is a light‐emission phenomenon from electrochemically excited luminophores generated by redox reactions. A solid‐state ECL electrolyte consisting of a network‐forming polymer, ionic liquid, luminophore, and co‐reactant is employed as the light‐emitting gate insulator of the ECLT. Based on this construction, high‐performance LETs that make use of various conventional non‐emissive semiconductors (e.g., poly(3‐hexylthiophene), zinc oxide, and reduced graphene oxide) are successfully demonstrated. All the devices exhibit a high mobility (0.9–10 cm2 V−1 s−1) and a uniform light‐emission. This innovative approach demonstrates a novel LET platform and provides a promising pathway to achieve significant breakthroughs to develop electronic circuits and optoelectronic applications.

The ionic liquid gel solvent was prepared by adding silica nanopowder in liquid Ru(II) complex. The ZnO/TNT nanotubes were fabricated by anodic oxidation method. The ECL cell-based silica gel type on ZnO/TNT electrode is composed as F-doped] mixed silica gel type / ZnO/TNT electrode film / FTO glass.The morphological and structural properties of ZnO/TNT electrode film were confirmed to the successful by scanning electron microscope (SEM), X-ray diffraction and spectral brightness analyzer. The threshold voltage at light emission start was 2.0 V for ZnO/TNT that was lower than 2.24 V for zinc oxide (ZnO), 2.25 V for TiO 2 nanotube (TNT) and 2.75 V for bare FTO. The luminance and electrical properties of the ECL cell-based silica gel type with ZnO/TNT electrode were 253 cd/m 2 for light intensity, 64 mA for output current, and 0.55 lm/W for ECL efficiency At 4 Vac 60 Hz. The peak intensity of the ECL cell-based silica gel type with ZnO/TNT electrode at wavelength was 622 nm which responded to dark orange color and had no effect on electrode layers.The ZnO/TNT electrode for ECL cell can increase an ECL efficiency and long lifetime stability.
