| dc.description.abstract | In this work, the europium doped Zinc tellurite glass was prepared by using the melting quenching method. Raman spectroscopy observe the vibrational modes, three main characteristic Raman peaks at 432 cm-1, 667 cm-1 and 744 cm-1 observed in all the samples. PL spectroscopy defines the emission behavior of the material, maximum photoluminescence intensity was observed in the hypertensive transition 5D0 - 7F2, indicating that the strong chemical interaction between the Eu3+ ion in T2, and T3 sample. The performance of the p3ht-pcbm61 solar cell improves from 1.75% to 1.84 percent (approximately 6%), and to 1.78% when covered solar cell with Eu3+doped tellurite glass and Eu3+doped tellurite glass containing gold nanoparticles, respectively. Whereas, UV-Vis spectroscopy defines absorption behaviour of the material, calculated the band gap of prepared glass sample are 3.1eV, 2.3eV, and 2.7eV for T1, T2, and T3, respectively. | |
