 The chemical bath deposition method was used to synthesize lithium niobate nanostructures, which were then decorated with silver nitrate particles through UV activation. The X-ray diffraction confirmed the hexagonal structure of the samples, while the optical absorption indicated the presence of silver atoms at 350 nanometers. The photoluminous peaks were observed at 355 nanometers for purely NbO3, Psi and 358, 360, 363, 371, 476 nanometers for different immersion times. Scanning electron microscopy showed that the particle morphology changed with increasing immersion time, while atomic force microscopy revealed a decrease in surface roughness. FTIR spectra showed an increase in the intensity of the peaks, while Raman spectroscopy indicated a shift in the peak positions. Finally, A.G. Li NbO3, Psi-heterojunction nanodevices were fabricated and demonstrated improved optoelectronic properties compared to pure Li NbO3 or Psi-heterojunction devices.
