Abstract

We report a new method for the synthesis of photoluminescent SrAl(2)O(4):Ce(3+), Dy(3+), Eu(2+) 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.
