Abstract:

The basic features of nanophosphors specified by their structural state are propounded. New era in determination of absorbed dose is emphasized by using nanophosphor Lithium Tetraborate dosimeters. They can be used for measuring absorbed dose of ionizing radiations more efficient than known micro-scaled materials in medical, personal and environmental dosimetry. The effect of a high concentration of surface trapping centers and grain size of particles on the nanophosphor luminescence characteristics is noted. These features determine some effective Thermoluminescence properties, which are essential for radiation detection. They show enhancement in the luminescence yield and increase of radiation resistivity. The luminescence and dosimetric properties of nanophosphors of different compositions are described. It is noted that nanophosphors show promise results as an advanced material for detecting ionized radiation doses
