Description
Summary:The combustion procedure was used to synthesize Bi Al O :Eu phosphors. The XRD and photoluminescence properties are investigations. The XRD patterns consist of an orthorhombic crystal structure. At 395 nm, the maximum excitation intensity was obtained. Following 395 nm excitation, two different emission peaks at 593 and 615 nm were observed. Concentration quenching occurred at 0.5 mol % Eu ions. The CIE coordinates for the Bi Al O phosphor with Eu ion doped are 615 nm (x = 0.680, y = 0.319) falling in the red region. According to the photoluminescence results, Bi Al O :Eu phosphors might be useful in the fields of near UV-excited w-LEDs.
