INTRODUCTION Int. J. Bio-Inorg. Hybr. Nanomater
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. Objective: They can be used for measuring absorbed dose of ionizing radiations more efficient than known micro-scaled materials in medical, personal and environmental dosimetry. Methodology: Lithium carbonate reagent and boric acid were used as precursors. Poly vinyl pyrrolidone (PVP) was used as a
... VP) was used as a capping agent to reduce the agglomeration of the particles. Besides, nitrate of copper (II) were used as dopants. Deionized water was used as the solvent. All materials which, utilized without any further purification, were purchased from Sigma Aldrich Company (United Kingdom) with purities more than 99.8% and used without further purification. Results and Discussion: 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. The luminescence and dosimetric properties of nanophosphors of different compositions are described. It is noted that the consequence nanophosphors show promise results in linearity as an advanced material for detecting efficiently ionized radiation doses.
