چکیده انگلیسی
In this paper, the Ca2SnO4:Eu3+ phosphor was prepared by low-temperature sol-gel method. The influence of calcined temperature and time on structure of Ca2SnO4:Eu3+ was investigated by using X-ray powder diffraction (XRD). The experimental results show that the dried gel was crystallized to the pure orthorhombic phase after calcination at 900 °C in air for 6 h. These phosphors have displayed bright red color under a UV source. The richness of the red color has been verified by determining their color coordination from the CIE standard charts, and this red emission has been assigned to 5D0â7F2 electric dipole transition at 616 and 620 nm. The excellent luminescence properties make it possible as a good candidate for plasma display panel (PDP) application.
