A new oxyapatite red phosphor Eu3+-doped Ca3Y7(BO4)(SiO4)5O∶Synthesis,structure and luminescence properties
文献摘要：
A series of new oxyapatite red phosphors Ca3Y7(BO4)(SiO4)5O doped with different concentrations of Eu3+were successfully synthesized by high temperature solid state method.The X-ray diffraction(XRD)Rietveld refinement results show that the structure of the phosphor belongs to space group P63/m and Eu3+ion replaces Y3+ion.The emission spectrum consists of the characteristic emission peaks corre-sponding to Eu3+under the excitation of 274 nm and the dominant emission peak is at 614 nm(5Do→ 7F2 of Eu3+).The concentration quenching effect occurs and the optimized Eu3+concentration is 4.0 mol％.The energy level diagram for luminous mechanism is also given and the non-radiative energy transfer mechanism between Eu3+is mainly exchange interaction.The CIE coordinate is close to the ideal red light and the color purity is higher than 99.79％.Moreover,the phosphor exhibits moderate thermal stability because the photoluminescence intensity at 423 K is still maintained at higher than 78.97％of that at room temperature.The internal quantum efficiency of Ca3Y7(BO4)(SiO4)5O∶4.0 mol％Eu3+phos-phor is 58.2％.A red light emitting diode(LED)device based on it can emit bright red light.The CCT values of the device are basically unchanged when driven by various bias current.The results show that Ca3Y7(BO4)(SiO4)5O∶Eu3+is a new type of oxyapatite red fluorescent material with good comprehensive performances.
