- W2281479178 abstract "The luminescence and energy transfer properties of Bi{sup 3+}, Eu{sup 3+}, and Dy{sup 3+} were studied in C-Y{sub 2}Si{sub 2}O{sub 7}. At room temperature, the Bi{sup 3+} shows luminescence mainly in the ultraviolet spectral region, with maximum emission wavelength at 372 nm ({sup 3}P{sub 1}-{sup 1}S{sub 0}) and a Stokes shift of 7200 cm{sup {minus}1}. In agreement with the low local symmetry (C{sub 2}), the hypersensitive transitions of Eu{sup 3+} {sup 5}D{sub 0}-{sup 7}F{sub 2} (red) and Dy{sup 3+} {sup 4}F{sub 9/2}-{sup 6}H{sub 13/2} (yellow) dominate in their emission spectra, whose lifetimes are 2.49 and 0.75 ms, respectively. Energy transfer phenomena were observed from Bi{sup 3+} to both Eu{sup 3+} and Dy{sup 3+}, and the energy transfer efficiency from Bi{sup 3+} to Eu{sup 3+} is higher than that from Bi{sup 3+} to Dy{sup 3+}. This result was explained by quantitative calculation." @default.
