Abstract
The SrAl2O4:Eu2+,âDy3+ nanowire was successfully synthesized by means of catalyst-assisted thermal chemical vapor deposition method. Their morphology, structure, composition, luminescent properties are explored in way of SEM, TEM, XRD and PL analysis. The nanowires diameter is uniform distributed in 50â¼80 nm, but orientation distribution is irregular, with the length varying from 4 μm to 20 μm. When heated up to the temperature of 1200â°C for three hours, the optimum synthesis is achieved with the alumina substrate covered by Al nanoparticles. The emission peak reaches to 517 nm with 365 nm light excitation and the luminous intensity was down to 1/10 of the initial brightness in 20 mins. The dielectric property was investigated at the room temperature, which show stronger dielectric loss ability.
