“…Photocatalytic degradation of organic pollutants has drawn a lot of interest among these various techniques for treating dyecontaminated water [8] due to its cost-effectiveness, reusability, and environmental friendliness [9,10]. With this technique, organic contaminants are broken down or oxidized into less dangerous or non-hazardous compounds [11].…”

It is crucial to find effective solutions to environmental contamination that are also ecologically friendly. Zinc oxide (ZnO) is well-known as a good photocatalyst. In this work, ZnO microspheres were synthesized using the solvothermal technique. X-ray diffraction (XRD), UV-Vis, and scanning electron microscopy(SEM) were used to evaluate the structural, optical, and morphological features of ZnO microspheres . The hexagonal structure of ZnO was determined using XRD analysis. The crystal size of ZnO was calculated using XRD patterns and was found to be 44.27 nm by the Debye-Scherrer equation, 32.39 nm using the Williamson Hall model, and 9.92 nm by the Modified Scherrer formula. The SEM pictures of the manufactured ZnO revealed that it has a shape in the form of microspheres formed by the conjunction of hexagonal nanorods. The average diameter of these microspheres is 5.16 μm. ZnO has a band gap energy of 3.1 eV. The photocatalytic activities of ZnO microspheres against methylene blue and Rhodamine B dyes were examined. Under sunlight, photocatalytic removal rates for methylene blue after 90 minutes and Rhodamine B after 120 minutes were 98.95% and 98.62%, respectively.

This study explores the impact of incorporating oxyethylene (OE) chains into rhodamine‐based dye molecules for the enhancement of photophysical properties in the context of chemical sensing. The introduction of OE chains provides several advantages, including improved water solubility, photostability and resistance to self‐assembled nanoaggregates formation. Despite these, the compound with oxyethylene chains showed poor response (~2‐fold) towards Hg2+ ions than that of dimeric probe (~20 fold) with no such substituents. Notably, dimeric compound shows a remarkable three‐fold larger response to Hg2+ ion compared to monomeric compound. This intriguing outcome is attributed to the extended conjugation within the dimeric structure, which can induce conformational change of the overall molecule. Moreover, the study investigates the effects of end substituents, such as electron‐donating (‐OMe, improved response) and electron‐withdrawing (‐NO2, poor response) groups, on the interaction with Hg2+ ions. The excellent sensitivity of the probe molecules is also evident in significantly low detection limits for Hg2+ ion (5‐8 ppb) in real‐life water samples. The high recovery values (> 95%) with sufficient low standard deviation (< 5%) indicates that quantitative analysis of Hg2+ is achievable using the current protocol. Beyond that, we have employed the probe 1 for intracellular (HEK293T cells) fluorescence imaging of Hg2+.
