中文摘要	a novel red phosphor based on eu(3+)-activated srcasio(4) was successfully synthesized by conventional solid state reaction method and the photoluminescence properties were investigated. x-ray diffraction (xrd) patterns indicated that srcasio(4):eu(3+) phosphors belong to orthorhombic crystal system (space group=pmnb). the photoluminescence (pl) excitation spectrum showed broad-band absorption and the strongest excitation peak at 397 nm contributed to the (7)f(0)->(5)l(6) transition which matched well with the emission of a uv chip. the pl emission spectrum with the peaks at 577, 586, 592, 612, 650 and 685 nm, were probably attributed to the transitions from (5)d(0) to (7)f(j)(j=0, 1, 2, 3, 4) of eu(3+) ions. the quenching concentration of eu(3+) was 10 mol.%, and the critical distance (r(c)) was about 1.2 nm. the fluorescence lifetime of eu(3+) ions was found to be 3.2 ms. the results indicated that the srcasio(4):eu(3+) might become an important red phosphor candidate for white-light-emitting diodes with near-uv led chips.
