“…Luminescence could be attributed to f-f or f-d transitions of rare earth ions and their intensity would depend on the site symmetry or nature of ligands [2]. 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.

“…The dominant wavelength is the single monochromatic wavelength that appears to have the same colour as the light source. The dominant wavelength can be determined by drawing a straight line from one of the CIE white illuminants (Cs (0.3101, 0.3162)), through the (x, y) coordinates to be measured, until the line intersects the outer locus of points along the spectral edge of the 1931 CIE chromatic diagram [15][16][17][18]. …”

“…Moreover, rare-earth ions in different host lattices prompted the development of rareearth luminescent materials for lamps, cathode ray tubes, dosimetry, scintillators, bio sensors and white light-emitting diodes [1][2][3][4][5]. Yttrium oxide (Y 2 O 3 ) possesses high refractory properties with melting point of ~2723K and thermal conductivity of 33Wm -1 K -1 .…”

ABSTRACTconcentration up to 0.4 mol% in Y 2 O 3 and thereafter it decreases with further increase of Er 3+ concentration. Also, the intensity of low temperature TL glow peak (~422 K) increases with increasing ion fluence up to 1×10 12 ions cm -2 and decreases with further increase of ion fluences. The TL trap parameters were calculated by glow curve shape method and the deconvoluted glows were exhibit of second order kinetics.
