Low-voltage cathodoluminescence properties of Y3Al5O12:Tb nanopowders

Tb3+-doped yttrium aluminum garnet (Y3Al5O12, YAG) nanocrystallites were synthesized by modified Pechini method. The XRD patterns were taken to examine the structure and to determine the average grain size of obtained nanocrystals. The photoluminescence spectra of nanocrystalline powders were measur...

Description
Summary:Tb3+-doped yttrium aluminum garnet (Y3Al5O12, YAG) nanocrystallites were synthesized by modified Pechini method. The XRD patterns were taken to examine the structure and to determine the average grain size of obtained nanocrystals. The photoluminescence spectra of nanocrystalline powders were measured. The obtained powders were electrophoretically deposited on ITO-glass slides. The cathodoluminescence spectra of deposited layers were taken and compared to powders. The influence of grain size on low-voltage ( < =1.5kV) cathodoluminescence of Tb3+-doped Y3Al5O12 nanocrystallites was observed. A possible application of obtained layers in field emission displays (FED) is briefly discussed.
