Synthesis and luminescence properties of needle-like SrAl2O4:Eu, Dy phosphor via a hydrothermal co-precipitation method

Needle-like SrAl2O4:Eu2+, Dy3+ phosphors had been prepared by calcining the precursors obtained from hydrothermal process at the temperature of 1100?C in a weak reductive atmosphere of active carbon. The crystal structure, morphology and optical properties of the composites were characterized.
