Effective Energy Transfer

A series of single-phase Sr5(PO4)3F: Eu2+, Tb3+, Na+ phosphors have been synthesized by high temperature solid-state reaction. The photoluminescence excitation and emission spectra, concentration effect and energy transfer from Eu2+ to Tb3+ are investigated in detail. The work shows that there is an effective energy transfer from Eu2+ to Tb3+, where Eu2+ reveals an intense excitation band from 280 nm to 400 nm, matching well with the emission of n-UV chips, and Tb3+ emits an intense green emitting light.

The phosphors YBO3:Eu with different morphology was successfully realized by mild hydrothermal process with different reaction condition. Highly spherical shape, uniform size and non-agglomeration of YBO3:Eu phosphors particle was obtained at 260°C,which is about 850°C lower than that by solid state reactions. The result of XRD showed that all samples were single phase with vaterite type structure. From IR and NMR spectra, it could be concluded that YBO3 contains mainly BO4 tetrahedra which is in favor for absorption VUV excitation. Monitoring by 598nm emission, the main excitation peak at about 247nm was observed in the excitation spectrum of spherical Y0.95Eu0.05BO3. Correspondingly, under 247nm excitation, the main peak at about 598nm was observed. The photoluminescence intensity (5D0→7F1 transition of Eu3+) of spherical shape of Y0.95Eu0.05BO3 was 1.5 times in comparison with which prepared by solid-state reactions. The best photoluminescence intensity was obtained when the concentration of Eu3+ is at 20 at. %. It indicated that hydrothermal method have a potential in the preparing various particles phosphors for application in displays and lamps.
