Sol‐Jel ile Sentezlenmis Er3+:Y2Si2O7 Nanofosforların Spektroskopik Özellikleri Üzerinde Konsantrasyon ve Faz Etkileri

Concentration and Cyrstalline Phase Effects on the Spectroscopic Properties of Sol‐Gel Synthesized Er3+:Y2Si2O7 Nanopowders

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 Ԩ and 1450 Ԩ, respectively. The photoluminescence properties were also investigated in terms of sintering temperature and doping effect on different polymorphs.
