Abstract: The LaCePO₄:Dy³⁺ luminescence experiments revealed the excitation peak at 275 nm which gives the emission spectra in visible region with intensive peaks centered at 475 and 573 nm. The emission spectra showed the transition from ⁴F_9/2 to the ground energy state. The prepared phosphor may be useful for display applications in white light emission and thermoluminescence dosimeters.

Keywords: LaCePO4:Dy3+ phosphors, solid state lighting, XRD, SEM, CIE, white light emission.
