“…The uorescence assay is the best choice with the above advantages. [5][6][7][8][9] Among them, carbon quantum dots are the best choice because of their superior uorescence properties and high speci city for detection. [6] In recent years, carbon quantum dots have been successfully used for the detection of some speci c substances because of their microscopic size, tunability of surface functionality, as well as their low toxicity and abundant synthesis methods.…”

A new highly uorescent hybrid material (CD@Eu-MOF) was synthesized by encapsulating CD (Carbon Dots) prepared from citric acid and ethylenediamine on the basis of a metal-organic framework prepared from Eu 3+ and 1,2,4-benzenetricarboxylic acid. The prepared composite not only maintains the excellent uorescence properties of CD and Eu 3+ respectively, but also forms a dual-emission uorescence system, and the system has good stability in aqueous solution. It was further used as a novel uorescent probe for the detection of Fe 3+ , which can effectively exclude the interference of other metal ions from the detection, and the intensity ratio of I Eu /I CD of CD@Eu-MOF material has a good linear relationship with Fe 3+ in the range of 1-200 μM. In this study, computer vision and BP (Back Propagation) neural network were used to train and t the sample data, and it was veri ed that the actual uorescence color of CD has a good linear relationship with Fe 3+ concentration. In addition, the BP neural network also veri ed that the uorescence spectrum data of CD@Eu-MOF also has a good linear relationship with Fe 3+ concentration.This study provides a new method for the fabrication of ratio and colorimetric Fe 3+ uorescence sensors, and provides a feasible solution for the simple and visual detection of Fe 3+ in the environment.

In this work, a voltage-heating actuated flexible solvatochromic film is developed using the composites of Nafion film-nickel complexes with spray-coated silver nanowires (AgNWs). The nickel complexes, inside Nafion film through ion exchange, serve as colorable components due to the coordination number change of water molecules in solvatochromism. The color-changing process of the composites was characterized experimentally by adjusting the water content in films, which exhibit distinct coloration properties from red to green with an absorbency shift (0.25–0.60 at 420–550 nm). To achieve an electrical actuation, the electrothermal joule effect of AgNWs is studied to accelerate the hydrolysis of the nickel complexes. A mask patterned spraying process is developed to increase the adhesion between AgNWs and Nafion film, which can be beneficial in a low (2–5 V) voltage-regulated coloration. This study provides a systematic investigation of flexible electrothermally responsive color-changing film of complex metal ions, the composite film prepared from flexible smart materials and well-adhered electrodes have potential applications in the fields of adaptive camouflage, wearable display devices and e-skins.
