Abstract

In this work we synthesized the Eu3+ doped Ca14Al10Zn6O35 phosphor using solution combustion method. Using powder XRD pattern and SEM was confirmed. Intrinsic absorption due to 4f-4f transition of Eu3+ results intense red emission from α-Ba3Y1-X(BO3):XEu3+makes it suitable for pc-WLED and confirms centro-inversion symmetry site of Eu3+ in host. Red emission at NUV excitation from Ca14Al10Zn6O35: Eu3+results from cross relaxation of Eu3+in host Entire work confirms the importance of synthesized phosphor along with previously reported same host materials. The reported phosphor may be suitable for NUV converted WLED, wavelength conversion devices and high power RGB –WLED.
