Summary, etc. <p class="Abstract"><span>Terbium doped strontium yttrium borate phosphor is prepared by solution combustion method. Structural characterization of Sr</span><span>3</span><span>Y(BO</span><span>3</span><span>)</span><span>3</span><span>:Tb</span><span>3+ </span><span>(SYB:Tb) has been carried out with X-ray powder diffraction (XRD) analysis. Particle size of 0.5–2 µm and perfect element composition were seen in SEM-EDS. Using FTIR at room temperature the presence of [BO</span><span>3</span><span>]</span><span>-</span><span> group; complete combustion of nitrates, organic material, absence of O-H bond were firmed up. Photoluminescence properties of the phosphor have been investigated by measuring the excitation and emission spectra. Several luminescence bands of Tb</span><span>3+</span><span> ions are observed under 233 nm excitation wavelengths in 350–700 nm spectral region. The emission spectra were composed of three bands, in which the dominated emission of green luminescence SYB:Tb attributed to the transition </span><span>5</span><span>D</span><span>4</span><span>→</span><span>7</span><span>F</span><span>5</span><span> is centered at 543 nm. The dependence of the emission intensity on the Tb</span><span>3+</span><span> concentration for the Sr</span><span>3</span><span>Y</span><span>1-X</span><span>(BO</span><span>3</span><span>)</span><span>3</span><span>:</span><span>x</span><span>Tb</span><span>3+</span><span> (0.01 ≤ x ≤ 0.05) was studied and observed that the optimum concentration of Tb</span><span>3+</span><span> in phosphor was 3 mol% for the highest emission intensity at 543 nm. The CIE coordinates (X=0.251363409, Y=0.736605581) fall at the border of green region in the CIE 1931 chromaticity.</span></p>
