Abstract

The white phosphor matrix 4SrO·7Al2O3 has been synthesized by firing the appropriate mixture of SrCO3, Al(OH)3 and H3BO3 in the molar ratios 1 : 3.5 : 0.135 at 1300°C for 4–7 h. The crystal structure of 4SrO·7Al2O3 has been determined as a orthorhombic Pmma space group with a = 24.7451(2) Å, b = 8.4735(6) Å, c = 4.8808(1) Å, V = 1023.41(3) Å3, Z = 2, and D = 3.66 g cm−3 by the Rietveld analysis. The refinement figures of merit are Rp = 8.26, Rwp = 11.60, Rbragg = 4.44 and s = 2.61 for 844 reflections with 2θ < 119.94°. And the corresponding X-ray powder diffraction data are presented for search/match analysis.
