Abstract

The Photoluminescence (PL), FFTIR, Raman characterization, XRD and TEM of Er doped nanocrystals (Y₃Al₅O₁₂:Er) prepared by glycolate method modified with PVA and UREA is reported. Irregular morphology was observed but for some concentration of PVA and UREA nanorods was observed, being PVA dominant in final morphology. XRD patterns show the presence of hexagonal phase of YAG (YAH) when the UREA was used but pure YAG crystalline structure was obtained with only PVA. Raman spectroscopy confirms the crystalline phase and in combination with infrared spectroscopy the presence of oxygen deficiency was observed. Strong green emission was observed as a result of the upconversion mechanism due to the two photon process. Luminescence results show that both PVA and UREA do not modify the emission properties but control the morphology.
