Year: 2023
Type: conference-paper
Abstract: Eu3+, Eu2+ and Ce3+ doped K3YSi2O7 phosphors are synthesized under reducing atmosphere. Photoluminescence properties show K3YSi2O7:1%Ce, 1%Eu at 330 nm excitation (FWHM = 211 nm, where FWHM stands for the full width at half maximum) can produce broadband emission. The preferential occupation sites of Ce and Eu ions in K3YSi2O7 are calculated using the bond energy theory. Eu2+, Eu3+, Ce3+ ions preferentially occupy K3, Y2, K1 sites, respectively. The broadband emission of the phosphor is caused by the dopant ions’ selective site occupancy.
