“…Table 2 presents the Judd-Ofelt parameters and the quality factor for some glasses doped with Nd 3+ for comparison with our results [14,[16][17][18][19]. The X 4 /X 6 ratio for the glass studied in this work (0.87) is comparable to ED2 glass (a commercial Nd 3+ doped phosphate glass) [19] and also to the fluorozirconate glass [17].…”

“…As a matter of fact, the recorded spectrum at 300 K is similar to those generally observed in glass materials or in disordered host lattices [22,23]. Three main absorption bands are located in the vicinity of 580, 750 and 800 nm.…”

“…The excitation wavelength in this case and the V-type center defect level is not resonant with any Er 3+ energy level so there is no Er 3+ ion emission in the visible. In the case of Nd 3+ , although both the excitation wavelength and the V-type center level correspond to the 2 K 15/2 , 4 G 11/2 , and 4 G 9/2 levels, the absorption coefficient for these levels is negligible [27,28] so excitation either through direct optical absorption or through energy transfer from the V-type centers does not take place in H3 and H4.…”

Er-, Nd- and Tm-doped Si-yttria stabilized zirconia (YSZ) thin film samples were prepared by rf co-sputtering. Chemical composition of the samples was determined using energy-dispersive spectroscopy (EDS) and the structure of the films by x-ray diffraction (XRD). The samples were annealed to 700 °C. Photoluminescence (PL) measurements were performed for the visible and infrared. Excitation with 457.9 nm produces spectra in the visible range due mostly to defects in the YSZ matrix with a weak Si nanoparticle surface state emission; the Tm-doped samples also present emission. Excitation with 488 nm produces spectra in the visible range with additional rare earth emissions such as the and emissions for the Er-doped samples and the emissions for the Nd-doped samples. The Er-doped samples present weak emissions and narrow emissions in the infrared range, while the Nd-doped samples present and emissions. No Tm3+ emissions in the infrared were observed. Excitation wavelength dependence measurements for the emissions show that these are due to energy transfer from the defects in the YSZ as well as from the Si nanoparticles while the same measurements for the emissions show that these are due to energy transfer from the Si nanoparticles only. Excitation flux dependence measurements for the and emissions show the sub-linear dependence characteristic of rare earth ion excitation through energy transfer from Si nanoparticles. emission dependence on emission showed that the former was possibly due to a combination of downconversion from higher levels of the Er ions, energy transfer from Si nanoparticles and upconversion transfer processes. We concluded that Er-, Nd- and Tm-doped Si-YSZ are promising materials for photonic applications, being easily broadband excited using low pumping powers.
