| Abstract: | A convenient high temperature solid-state reaction method was developed to fabricate Na1-xAl1-xSi1+xO4:Eu2+ phosphors.The as-prepared products were characterized by X-ray diffraction(XRD),photoluminescence(PL),and photoluminescence excitation(PLE).The luminescence of Na1-xAl1-xSi1+xO4:Eu2+ phosphors were characterized by the two corresponding emission centers at 535 and 440 nm.The excitation spectrum extended from 250 to 400 nm.A white light was observed by naked eye upon ultraviolet excitation.The relative... |
