In this paper, synthesis and characterizing of bismuth oxide nanoparticles (Bi(2)O(3)NPs) are synthesized by laser ablation at different laser pulses energy 200, 400, 600 and 800 mJ with 100 shots and laser wavelength 1064 nm and porous silicon (PS) was presented. Scanning electron Microscopy (SEM), x-ray diffraction (XRD), UV-vis-NIR spectrophotometer and electrical properties are used to characterize the products. The results show X-ray patterns analysis and improve the crystalline structure of Bi2O3 nanoparticles which relate to alpha-phase and monoclinic symmetry. SEM image shows approximate spherical particles with a little agglomeration for both samples. From results transmittance of Bi(2)O(3)NPs suspension with energy bandgaps ranging from the infrared up to near-ultraviolet can be obtained, depending on their structure and morphology. Based on these results, we demonstrated enhanced performance of Bi(2)O(3)NPs/PS photoddetectors over a broad range of wavelengths.
