This study presents a broadband photodetector that combines a bimetallic Copper Molybdate (CuMoO4) thin film with Zinc Sulfide Quantum Dots (ZnS QDs) on a flexible paper substrate. The ZnS QDs, synthesized through a co-precipitation technique, capitalize on their nanoscale properties, which arise from quantum confinement effects. When integrated with the CuMoO4 thin film, these quantum dots significantly enhance the optoelectronic performance of the device. CuMoO4, with its 1.9 eV bandgap, is highly sensitive to light in the visible and infrared regions of the spectrum. The incorporation of ZnS QDs further extends the device’s sensitivity into the ultraviolet range, enabling it to detect a broad spectrum from UV to IR within a compact configuration. The device demonstrates impressive responsivity values of 109.7 mA/W (UV), 328.44 mA/W (visible), and 33.19 mA/W (IR), along with high detectivity figures of 7.1x1011 Jones (UV), 19.3 x 1011 Jones (visible), and 1.9 x 1011 Jones (IR) under respective light intensities of 2.9 mW/cm2, 0.013 mW/cm2, and 9.945 mW/cm2.

Therefore, this study employs molecular dynamics simulations to investigate the effects of defect types and functional groups on graphene-filled vinyl silicone rubber (MVSR) composites. Additionally, it elucidates the competitive mechanisms of surface modification on the destruction of interface structure and the improvement of thermal conductivity. The results indicate that the interfacial thermal conductance (TC) of the divacancy GE/MVSR composites is lower than that of the monovacancy GE/MVSR composites when the concentration of vacancy defects is 2.2%. Moreover, when the structural defects of graphene are reconstructed, the TC of the composite material is reduced. When the grafting ratio is 4.8%, the thermal conductivity of the carboxylated graphene (GE-COOH)/MVSR composite material is maximized compared to other functional groups. When the carboxyl grafting ratio is 19.9%, the thermal conductivity of the composite material increases by 30% compared to pure MVSR.

As-synthesized HEO nanoparticles in pyrochlore structure, exhibit excellent thermal stability and structural integrity when annealed at 800 °C. The composites were prepared by adding different weight percentages (5, 10, 15, and 20 wt%) of as-synthesized HEO nanoparticles with HDPE matrix and studied their phase, microstructure, and mechanical properties.
