Abstract
A chipless radio frequency identification (RFID) photosensitive sensor composed of zinc oxide (ZnO) / graphene oxide (GO) / cadmium sulfide (CdS) nanocomposites is designed and fabricated for remote monitoring of light in the environment. The label consists of a dielectric layer, a resonant structure, and a sensitive layer. The dielectric layer is made of inexpensive epoxy resin. By replacing the parallel plate capacitance of the traditional ELC resonator with the interdigital capacitance (idc), an ELC idc resonator with a larger capacitance per unit area is obtained and optimized by HFSS simulation. The label is evaluated using a vector network analyzer, and the experimental results confirm the feasibility of the photosensitive label. In the light environment of 0–49 klx, the sensitivity of the photosensitive label is 895.31 Hz/lx thus meeting the requirement for the monitoring of environmental light.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
