Enhanced photoluminescence is observed in Eu3+/Sm3+ co-doped CaLa4Ti4O15 phosphors, significantly boosting effectiveness for white light-emitting diodes.
The peak photoluminescence intensity shows a remarkable increase, correlating with the optimal concentration of co-doping elements for peak performance.
Synthesis involves carefully controlled conditions to achieve the co-doping of europium and samarium in the host lattice, ensuring effective energy transfer.
This advancement in phosphor materials highlights the potential for more efficient white light-emitting diodes, enhancing their use in everyday lighting.
