Abstrakt: Barium yttrium phosphate (BYP) phosphor doped with trivalent praseodymium ions (BaY (1-x) (PO 4 ) 3 :Pr 3+ (x = 0, 0.01, 0.05, 0.1, 0.15, and 0.2 wt%) was synthesized using a high temperature solid-state reaction method. Structural properties were analyzed through X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. XRD patterns confirmed the structure of the synthesized phosphor and average crystalline size was estimated (approximately 63.8 Å). Vibrational functional groups were identified using FTIR spectroscopy. The emission spectrum was recorded under an 444 nm excitation wavelength, which showed various emission transitions of Pr 3+ ions. Commission Internationale de l'éclairage coordinates, colour purity, and colour correlated temperature values were calculated for the BYP:Pr 3+ phosphors and these coordinate values fell in the yellow region of the visible spectrum.
