Fluorescence of copper, manganese and antimony ions in phosphate glass host

Structural, mechanical and opto-thermal properties of non-crystalline SbxOy thin films

“…The refractive index, the dielectric constant as well as the plasma frequency of this oxide were also calculated. Moreover, the optical, mechanical and opto-thermal investigation results were in good agreement with those of XRD and AFM techniques and with some recently published results [44][45][46]. The relatively high c-axis oriented direction of grains of the highly annealed films has indeed a benefit effect on their opto-thermal properties via an obvious decrease of ψ AB values (≈−30%).…”

Characterization of Standard Reference Material 2943, Cu-ion-doped glass, spectral correction standard for blue fluorescence

“…This spectral shape is consistent with Cu-ion-doped glasses reported previously, although the positions and broadness of peaks have been found to change with the base glass composition [31,32]. Homogeneity of the glass was measured on a centimeter scale by collecting the spectrum for each SRM 2943 sample in both a normal and a raised (0.5 cm) position and by comparing them.…”

EPR, optical absorption and luminescence studies of Cr3+-doped antimony phosphate glasses

“…4, good fits (red solid line) were obtained for the luminescence spectra (open circles) of both pure and SbPO:Cr 3+ glasses using four Gaussian bands centered at 23,754, 22,740, 21,100, and 19,050 cm À1 , which are reported as a result of the spin-orbit and Jahn-Teller effect [35]. Also the Sb 3+ emission in the 350-550 nm region has been related to the antimony ions in octahedral and tetrahedral coordination in a phosphate glass host [36]. Additionally it can be observed that the dopant Cr 3+ ion does not alter significantly the luminescence spectra of antimony phosphate glasses when excited with 350 nm, with a little narrowing of the band centered at 22,470 cm À1 (445 nm), probably due to changes in the short ranged crystalline field around the antimony ions with increasing chromium concentration in the glasses.…”
