“…n the past decade, organic and inorganic semiconductor materials have attracted attention of many researcher scholars because these semiconductor materials demonstrated excellent electrical and optical properties. These materials have been used in light-emitting diodes, sensors, transistors, lasers, displays, photodetectors, highpowered devices, solar cells, memory and so on [1][2][3][4][5][6][7][8]. Given their wide bandgap, inorganic oxide-based semiconductor materials, such as In2O3 (3.7 eV), Ga2O3 (4.9 eV), ZnO (3.37 eV), NiO (3.9 eV) and WO3 (2.8 eV) have been utilised for optoelectronic devices [9][10][11][12].…”

Ultraviolet (UV) detection is an important index, as UV rays can cause skin diseases in humans. To enhance the performance of UV photodetectors, we fabricated palladium nanoparticles-(Pd NPs) modified ZnO nanorods. The surface morphology is observed by using transmission electron microscopy and transmission electron microscopy. The crystal structure is analysed by using X-ray diffraction. The optical property is investigated by using photoluminescence spectra. The Idark of the ZnO and Pd/ZnO samples was 5.05 × 10 -8 and 2.24 × 10 -9 A when a 1 V bias was applied. On the other hand, the Iphoto of the ZnO and Pd/ZnO samples was 2.56 × 10 -6 and 4.38 × 10 -6 A when the sample is illuminated UV light (365 nm). The current ratio of Iphoto / Idark for the ZnO and Pd/ZnO samples was 50.8 and 1960, respectively. The enhanced performance of the Pd NPs can produce a strong electric field after light is absorbed via the localised surface plasmon resonance effect.
