Photoluminescence and thermoluminescence of Ce3+ ions doped in LiAl5O8 and NaAl11O17 aluminate systems

► PL and TL studies of LiAl5O8:Ce and NaAl11O17:Ce phosphors. ► TL glow curves of LiAl5O8:Ce and NaAl11O17:Ce phosphors exhibit well defined TL peaks. ► They have 1.38 times and 5.69 times more sensitivity than CaSO4:Dy.
