“…The 266 and 488 nm excitation wavelengths are nonresonant lines with Nd 3+ ions so that only an indirect excitation of Nd trough the Si-np can occur. 6,14,16 TPLE measurements were performed using a 450 W xenon arc lamp as the excitation source, which was connected to a 0.18 m Jobin Yvon monochromator. The excitation power density was about 0.1 W / cm 2 in the 210-480 nm excitation range.…”

“…3 Unfortunately, whatever the host matrix, RE ions suffer from a low absorption cross-section as it has been reported in the case of Er 3+ ions 4,5 and Nd 3+ ions. 2,6,7 Since the discovery of the sensitizing effect of Si-nanoparticles ͑Si-np͒ toward RE emission, 8 RE-doped nanostructured Si-based films are promising for the achievement of future devices optically excited. Kenyon et al 9 demonstrated that the presence of Si-np in a SiO 2 host matrix resulted to an increase in the Er 3+ photoluminescence ͑PL͒ by a factor of 100 and an enhancement of the effective absorption cross section by four orders of magnitude.…”

The Nd-nanocluster coupling strength and its effect in excitation/de-excitation of Nd 3+ luminescence in Nddoped silicon-rich silicon oxide Appl. Phys. Lett. 83, 2778Lett. 83, (2003 We report on the microstructure and photoluminescence ͑PL͒ properties of Nd-doped SiO 2 thin films containing silicon nanoparticles ͑Si-np͒ as a function of the annealing temperature and the Nd concentration. The thin films, which were grown on Si substrates by reactive magnetron co-sputtering, contain the same Si excess. Fourier transform infrared ͑FTIR͒ spectra show that a phase separation occurs during the annealing due to the agglomeration of the Si excess resulting in the formation of Si-np. Besides, after annealing, the films exhibit PL from excitonic states confined in Si-np. We showed that the intensity of the PL of Nd 3+ ions that occurs at ϳ0.92, 1.06, and 1.4 m is maximal at low Nd concentration and while well-passivated Si-np are formed. FTIR and x-ray measurements showed that the increase in the Nd incorporation has detrimental effects on the PL of Nd 3+ because of the formation of Nd 2 O 3 nanocrystals and inherent disorder in the SiO 2 host matrix. PL excitation measurements demonstrate that the PL of Nd 3+ ions is nonresonant and follows the excitation of Si-np giving new evidence of the energy transfer from Si-np toward the rare earth ions.

“…Metal phosphate glasses are extensively studied due to the fact that they present non-linear optical, magnetic and electrical conductivity properties that provide them with several technological applications such as optical fibers with low loss, waveguides, laser glasses, and others [1][2][3][4]. Since pure phosphate glasses are unstable, antimony oxide is incorporated, providing enhanced chemical stability [5].…”

“…High transparency, considerable refractive index and dispersion like properties create phosphate glasses into prominent materials for application oriented device manufacturing. Besides these advantages, phosphate glasses have a best thermo-optical performance with considerable chemical durability, high gain as with low energy back transfer and weak upconversion [1][2][3][4][5] and flexible to prepare in different concentrations with proper luminescent active ions. Dy 3+ (4f 9 ) are one of the attractive ions among rare earth for the present spectroscopic studies.…”

The present work deals with optical absorption, luminescence studies of the cadmium zinc phosphate glasses doped with Dy 3+ ions. The effect of variation of LiF concentration in the host matrix cadmium-zinc phosphate glasses was established in this study. Optical absorption, luminescence studies reveals the emission of white light from the glass upon excitation. Characteristic nature of existence of Dy 3+ ions in the host with absorption bands in absorption spectra, excitation and emission spectra with chromaticity coordinates in the white light region was described. These prepared glasses were useful in white light generation materials.
