“…Rare earth doped luminescent materials find practical applications such as detectors, tunable LED's CFL, FEDs etc [3][4][5][6][7]. Among the rare earth ions, trivalent europium (Eu 3 þ ) has been recognized as an efficient red luminescent phosphor due to its 5 D 0 -7 F j (j ¼0, 1, 2, 3 and 4) transitions [8,9].…”

a b s t r a c tNanoparticles of Mg 2 SiO 4 :Eu 3 þ have been prepared by the solution combustion technique and the grain size estimated by PXRD is found to be in the range 40-50 nm. Ionoluminescence (IL) studies of Mg 2 SiO 4 :Eu 3 þ pellets bombarded with 100 MeV Si 8 þ ions with fluences in the range 1.124-22.48 Â 10 12 ions cm À 2 are carried out at IUAC, New Delhi, India. Five prominent IL bands with peaks at 580 nm, 590 nm, 612 nm, 655 nm and 705 nm are recorded. These characteristic emissions are attributed to the luminescence centers activated by Eu 3 þ cations. It is found that IL intensity decreases rapidly in the beginning. Later on, the intensity decreases slowly with further increase of ion fluence. The reduction in the ionoluminescence intensity with increase of ion fluence might be attributed to degradation of Si-O (n 3 ) and Si-O (2n 3 ) bonds present on the surface of the sample. The red emission with peak at 612 nm is due to characteristic emission of 5 D 0 -7 F 2 of the Eu 3 þ cations. Thermoluminescence (TL) studies of Mg 2 SiO 4 :Eu 3 þ pellets bombarded with 100 MeV Si 8 þ cations with fluences in the range 5 Â 10 11 ions cm À 2 to 5 Â 10 13 ions cm À 2 are made at RT. Two prominent and well resolved TL glows with peaks at $ 220 1C and $ 370 1C are observed. It is observed that TL intensity increases with increase of ion fluence. This might be due to creation of new traps during swift heavy ion irradiation.

“…Among the RE ions, trivalent europium (Eu 3+ ) has been recognized as an efficient red luminescent phosphors due to its 5 D 0 → 7 F J(=0, 1,2,3,4) transitions which are used in color television displays and mercury free-lamps [4,5]. In addition to the 5 D 0 transitions the higher 5 D ( 5 D 1 , 5 D 2 , 5 D 3 ) levels are rarely observed depending on the host lattice and the doping concentration [6].…”

“…Recently, studies on alkaline-earth stanates for the phosphor host materials of rare-earth activators have been proceeding and photoluminescence (PL) properties have been reported for CaSnO 3 :Eu 3+ , Pr 3+ , Tb 3+ [1][2][3], SrSnO 3 :Eu 3+ , Tb 3+ -Mg 2+ [1,4], Ca 2 SnO 4 :Eu 3+ [5,6], Sr 2 SnO 4 :Eu 3+ , Eu 3+ -Ti 4+ [4,7,8], and Ba 2 Sn O 4 :Eu 3+ [9]. Chen et al [5] synthesized (Ca 1Àx Eu x ) 2 SnO 4 solid solutions at 1100-1300 1C by solid-state reaction and showed the solution limit of Eu(x) at 0.07 by X-ray powder diffraction.…”
