摘要：

Calcium stannate oxide (Ca2SnO4) compound doped with Ce3+ rare earth ion was synthesized by conventional solid state synthesis method at 1300 degrees C. Phase confirmation and crystal structure analysis was done by obtaining its X-ray diffraction (XRD) pattern. The vacuum ultraviolet (VUV) visible spectroscopic properties were investigated. Ca2SnO4:Ce3+ phosphor possesses broad and strong absorption in VUV and UV region. Excitation peaks are present at 140nm, 174nm, 200nm and 261 nm. Ca2SnO4:Ce3+ exhibits intensive photoluminescence (PL) emission centered at 430 nm and 467 nm under VUV excitation. CIE chromaticity co-ordinates were calculated. The luminescence properties of Ca2SnO4:Ce3+ compound make it good candidate as a blue phosphor for mercury-free lamps and plasma display panel (PDP) applications. (C) 2017 Elsevier GmbH.
