Abstract: The near Infrared luminescent materials of Y_1.98-xYb_xEu_0.02O₃ (where x=0,0.01,0.02,0.04,0.06,0.10) were prepared through a facile, in-expensive pathway of sol-gel method, and the resultant samples were characterized and analyzed using X-ray diffraction(XRD) and fluorescence spectroscopy(PL). The results of X-ray diffraction indicated that the incorporation of ions of Eu³⁺ and Yb³⁺ only partially replaced the lattice sites of Y³⁺ without the change of the former cubic crystal structure of Y₂O₃. Under the chosen laser (466nm, the characteristic excitation wavelength of Eu³⁺) irradiation, the emission light of visible light emission and near-infrared from the resultant samples could be observed, where the samples of Y_1.94Yb_0.04³⁺Eu_0.02³⁺O₃ showed the higher luminous efficiency in the near infrared spectrum. The ions of Eu³⁺ and Yb³⁺ doped near infrared luminescent material were successfully prepared using sol-gel method, and the structure and luminous performance were systematically characterized. The resultant sample could efficiently convert high energy photons into NIR photon benefiting the improvement of the photoelectric conversion efficiency of the Si-solar cell. Thus, the problem of spectrum mismatch between solar spectrum and photoelectric response of silicon solar cells could be solved, and the novel near infrared luminous materials owned the promising prospect and broad application in the design and fabrication of novel high efficiency silicon solar cells.
