Synthesis and characterization of a new Dy3+ and Sm3+ doped SrGd2O4 down-conversion nanomaterial obtained via glycine-assisted combustion synthesis
Апстракт
In this investigation, down-conversion nanopowders of SrGd 2 O 4 doped with different concentrations of either Dy3+ or Sm3+ ions were examined. All samples were prepared via glycine-assisted combustion method, first burned at 500 ºC for 1.5h and additionally calcined at 1000 ºC for 2.5h, at ambient room temperature. The XRD analysis confirmed that all samples crystallize as single phase and the orthorhombic lattice SrGd2O4 . TEM analysis determined high degree of crystallinity of samples with grain size of approximately 200 nm for Dy 3+ doped and 150 nm for Sm 3+ doped SrGd2 O 4 . For both samples SAED showed that diffraction rings correspond to the hkl plane indices of SrGd 2 O 4 , while EDS indicated presence of Dy in crystal structure. Results of luminescent characterization demonstrated all appropriate emission peaks related to either Dy3+ or Sm 3+ dopant ions. Investigation of dopant concentration revealed that the lowest values of both dopants have the most prominent emission pea...ks, while coordinates obtained from the CIE diagram showed emission shifting with the change of concentration.
