TL response of nanocrystalline MgB4O7:Dy irradiated by 3MeV proton beam, 50MeV Li3+ and 120MeV Ag9+ ion beams

Thermoluminescence properties of Al2O3:Tb nanoparticles irradiated by gamma rays and 85MeV C6+ ion beam

“…This result is almost similar to that reported earlier [37]. From the dosimetry point of view these individual nanoparticles are much better than those in cluster form to avoid overlapping of radiation tracks [12].…”

“…The density of the medium traps becomes higher than the corresponding traps of gamma rays irradiated sample. The wide response of nanostructure materials was explained in an earlier work [7,8,12,37] and could be attributed to the tiny size of the nanostructures. These ultrafine sizes perhaps could minimize tracks overlapping.…”

“…For C ion beam irradiation the powder samples were prepared in pellet form. The procedure for making pellets and ion beam irradiation was described earlier [12]. The prepared pellets were of 0.66 mm (660 μm) thickness and 10 mm diameter.…”

“…Moreover, large number of these nanostructures were evaluated for different applications. In the field of ionizing radiation dosimetry, a good number of these nanostructures were produced and studied for their response to both sparsely and densely ionizing radiations [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These nanostructures were found to have excellent thermoluminescent (TL) dosimetric properties, particularly their response in a wide span of exposures.…”

“…This is due to different spatial dose distribution, which causes saturation effects in the case of densely ionizing radiation [30]. On the other hand several nanostructure materials showed saturations at only very high doses [7][8][9][10][11][12][13][14][15][16][17][18][19][20] and thus might be the ultimate choice for ion beam dosimetry mainly carbon ions beam.…”
