Abstract:

Terbium-Ytterbium ions (Tb3+-Yb3+) co-doped zinc-tellurite glass specimens were prepared by melt quench process for the investigation of down-conversion phenomenon. Using energy level analysis, fluorescence spectroscopy, and absorption spectroscopy, the investigation verified that a down-conversion mechanism was present in the system. 325 nm and 448 nm were the two excitation wave lengths at which down-conversion was examined. High-energy photons can be absorbed by Terbium ions, which then efficiently transfer the energy to Ytterbium ions. Both the photoelectric conversion efficiency and the energy transfer efficiency of solar cells were altered. Our findings indicate that the Terbium-Ytterbium ions co-doped zinc-tellurite specimen exhibits frequency down-conversion and have considerable potential for use in solar cell applications.
