Formation and characterization of ultrafine nanophosphors of lithium tetraborate (Li2B4O7) for personnel and medical dosimetry

The present study demonstrates an innovative single-step thermal synthesis of nano-sized lithium tetraborate dosimeter and its characterization. The optimum calcination temperature and time for the synthesis of the nanoparticles material was 750 °C and 2 h, respectively. Characterization of the samp...
