High‐quality (Y 0.05 Gd 0.05 ) 0.94−x Al x (V 0.25 P 0.75 )O 4 :Eu 0.06 (0≤x≤0.02) phosphors were synthesized by solution combustion method. We investigated their microstructure and photoluminescence properties as a function of Al 3+ content. The emission spectra consisted of three strong and sharp peaks at 594, 615 − 620, and 697 − 704 nm. These peaks were assigned to the transitions from the excited 5 D 0 to 7 F j (j = 1, 2, and 4) of Eu 3+ activator. The annealed phosphors formed a single phase with the tetragonal structure. The doped Al 3+ significantly improved the photoluminescence properties.
