Abstract
In the present work, a series of Ba2-xZn7F18:xmol%Eu3+ (x =0.1,0.5,0.7,1.0,15) phosphors were synthesized by combustion method. The spectroscopic properties of synthesized phosphor were observed by photoluminescence and photometric characterization technique. The obsearved excitation spectra revealed two bands around 395nm and 466nm that was attributed to the 7F0→5L6, and 7F0→5D2, transition oftrivalent europium ions, respectively. Under 395nm and 466nm excitation, the PL emission spectra shows several emission bands around at 580nm, 593nm and 613nm, which are ascribed due to 5D0→7F2, 5D0→7F1, and 5D0→7F2 transition of Eu3+ ions, respectively. The emission band of 613nm indicates the highest emission intensity compared to the other emission bands. The emission band revealed the highest emission intensity at 1mol% concentration of Eu3+ ions. Further, a CIE chromaticity diagram was obtained, which is confirmed that red emission. The entire investigation and their outcomes revealed that the synthesized phosphors exhibit strong red emission, which can be applied in the lighting industry and display applications.
