Abstract EN
The novel phosphor K2Y2B2O7 doped with europium is studied for its photoluminescence properties.
The studies show that the phosphor gives strong red emission (PL) at 613 nm related to 5D0-7F2 transition of Eu3+ under the 260 nm excitation (PLE) related to the charge transfer (CT) from the 2p orbital of the O2− ions to the 4f orbital of Eu3+ ions with CIE coordinates (x=0.675; y=0.324).
The results of PL and PLE spectra indicate the applicability of K2Y2B2O7:Eu as a red component in lamp phosphor.
The phosphor is characterized through XRD pattern analysis, and morphology is explained on the basis of SEM image.
Optimum concentration of Eu3+ required for the highest intensity of emission is also studied.
