“…The J-manifolds of Er 3+ ions are split due to the low symmetry (C1 or C2) of the Y2Si2O7 cation sites [25]. We observed that the spectral form and the count of the Stark components showed similar behavior for each Er 3+ ions transitions in the powders at each phase.…”

“…Rare earth elements (RE) doped, co-doped and tridoped Y2Si2O7 are crucial nanophosphors for lasers, light emitting diodes (LED), white LED and plasma display panel applications [13][14][15][16]. Although, various rare earth-activated yttrium orthosilicates have been studied a lot [17][18][19][20][21][22][23][24][25][26][27][28], there have been a few studies reported on the Er 3+ : Y2Si2O7. Diaz et al analyzed the luminescence properties of Y2Si2O7 : Dy phosphors prepared by a new pressureless hydrothermal route.…”

Nanosized yttrium disilicate powders activated with trivalent erbium ions were produced by Sol-Gel known as wet chemical process. The structure and morphology of the synthesized powders were characterized by using X-ray diffraction spectroscopy (XRD), Transmission electron microscopy (TEM) and Photoluminescence spectroscopy. The XRD analysis revealed that the formation of triclinic -Y2Si2O7 and monoclinic -Y2Si2O7 polymorphs were obtained at 1050 and 1450 , respectively. The photoluminescence properties were also investigated in terms of sintering temperature and doping effect on different polymorphs. Sol-Jel ile Sentezlenmis Er

“…Concerning the host matrix for these ions, there is a wide variety of materials such as silicates, aluminates, sulfides, oxides, phosphates, borates glasses, etc. [3][4][5][9][10][11][12][13] which have been doped with RE. These compounds, in general, are synthetized by different techniques such as spray pyrolysis [14], solvent evaporation [3][4][5], mechanochemical synthesis [15], soft chemical synthesis [16], solid state reaction at high temperatures in an inert atmosphere [6], vibrating milled solid-state reaction [17], coprecipitation method [18], etc.…”

Luminescent characteristics of Eu2+/Li+ doped (La-Al)2O3 phosphors and PMMA films activated with them

The effect of Li co-doping on the blue luminescence of Eu2+ doped (La-Al)2O3 phosphors and its incorporation into poly (methyl methacrylate) PMMA films are reported. The phosphors were synthesized by a simple two-step process in which the (La-Al)2O3 powders were obtained by an evaporation method, and the subsequent co-doping with Li+ and Eu2 were made through a solid state reaction in a reductive atmosphere at 1250 0C. The incorporation of those phosphors into PMMA matrix and the synthesis of films with thicknesses between 6 and 12 μm was made by drop-casting. The characteristic blue broad band emission centered at 440 nm associated with the 4f65d1→ 4F7 transition of Eu2+ ions (CIE coordinates 0.6731, 0.3343) was observed when these powders were excited with 297nm light. These luminescence intensity was enhanced when Li was incorporated as co-dopant up to 320% with respect to those phosphors without Li. The luminescent characteristics of these phosphors were preserved when they were embedded into the PMMA films.
