Wet chemical synthesis of BiPO 4 :Eu 3+ phosphor for w‐LED application

Abstract The synthesis of BiPO 4 :Eu 3+ phosphors has been achieved via a wet chemical process. X‐ray diffraction patterns show that the phase of the as‐prepared samples matches very well with the standard BiPO 4 structure. At 395 nm, the highest excitation intensity was observed. Following 395 nm e...

Summary:Abstract The synthesis of BiPO 4 :Eu 3+ phosphors has been achieved via a wet chemical process. X‐ray diffraction patterns show that the phase of the as‐prepared samples matches very well with the standard BiPO 4 structure. At 395 nm, the highest excitation intensity was observed. Following 395 nm excitation, two characteristic emission peaks at 592 nm and 616 nm were shown. At 0.5 mol% of Eu 3+ ions, concentration quenching occurred. The particle size is within the micrometre range, according to the scanning electron microscope magnification. The chromaticity coordinates for wavelengths 592 nm and 616 nm are (x = 0.586, y = 0.412) and (x = 0.682, y = 0.317), respectively. The findings imply that the prepared phosphor may be used to create white light‐emitting diodes.
