Abstract: We present a sustainable green synthesis approach for zinc oxide nanoparticles (ZnO NPs) utilizing Citrus hystrix leaf extract and their application as an active medium in thin film transistor (TFT)‐based ammonia gas sensor. For the first time, ZnO NPs derived from serve receptor layer (TFT) device, enabling selective detection at significantly reduced initiation temperature. The synthesized NPs, with wurtzite structure average crystallite size of approximately 14 nm, are deposited...
Flexible piezoelectric composites offer alternative and/or additional solutions to sensor, actuator and transducer applications. Here in this work, we have successfully fabricated highly flexible with poly dimethyl siloxane (PDMS) using herbal zinc oxide (h-ZnO) as filler having weight fractions up 50 wt.% by solution casting of dispersions h-ZnO PDMS. Excellent piezo properties (Resonant frequency 935 Hz, d*33 29.76 pm V−1), physiochemical (Wurtzite structure ZnO, 380 nm absorbance)...
We investigated the effect of reduced graphene oxide (rGO) doping on birefringence 5CB liquid crystal (LC). The characteristics synthesized rGO and LC-rGO composite with different concentrations were analyzed by atomic force microscopy, X-ray photoelectron spectroscopy, white light polarized voltage-dependent transmission measurement, differential scanning calorimetry. found that LC an appropriate concentration enhances LC. This is mainly due to improved anisotropy polarizability, which...
A novel approach to detecting infrared radiation has been developed that utilizes the photothermal effect in rGO-doped liquid crystal, capable of not only infrared, but also temperature change and energy deposited detector.
Quantum dots have diverse chemical properties with different ligands attached on the surface. The cysteamine has been used as a ligand for various quantum because it high solubility in water, and facilitates binding of dot gold However, hydrogen bonds cause aggregation capped dots. In this study, we suggested simple synthesis method aggregation-free PbS analyzed electric optical synthesized dot. This study potential to develop advanced dot-based sensor technologies, including biomedical...
Manipulating the phase and amplitude of light led to many important breakthroughs in optics, it is still considered one most critical technologies emerging optical systems. However, conventional modulators generally suffer from strong polarisation dependence that stems anisotropic property base material. Here, we report a modulator polarisation-independent based on trilayer birefringent materials which have their axes aligned at specific angles. The proposed structure effectively eliminates...
Multispectral plasmonic color filters were fabricated using nano-imprint lithography and benchmarked to similar with standard CMOS processing. The self-aligned process yields devices narrow linewidths below 30nm up 50% transmission efficiency.
