abstract

We report a new method for the synthesis of photoluminescent SrAl2O4:Ce3+, Dy3+, Eu2+ nanotubes, PL-SNT:Ce(III), Ln, using solid-state reaction and post-annealing approach. This new optical nanotubular structure was characterized by HRTEM, SEM, AFM, EDX, steady-state and time-resolved PL spectroscopy. A series of f-f and f-d-transitions with light emission in structured bands peaking at 488 nm arising from the polymorphism of the host lattice was correlated with an intercrystalline distal-effect on the afterglow phenomenon.

acknowledgements

We kindly acknowledge the CICECO Laboratory, namely the Physics Department for taking PL spectra, Dmitri Kiselev for AFM probing, and Dr Marc-Georg Willinger for a TEM support. SEM images were acquired in a SU-70 microscope (FCT/REDE/1509/RME/2005). This work was supported by the Ministry of Science, Technology and Higher Education of Portugal under a Doctoral Fellowship of the Research Institute of the University of Aveiro (BDUA/f2698/2006-2010).
