Effects of 90 MeV carbon ion irradiation on cadmium oxide quantum dots

摘要

Cadmium oxide (CdO) quantum dots were synthesized in the laboratory by quenching method using CdO powder sintered at 900 degrees C and ethyl alcohol kept at ice-cold temperature. X-ray diffraction studies revealed the NaCl cubic structure of CdO quantum dots. The CdO crystallite size was estimated to be 2.7 nm. Heavy ion irradiation using 90 MeV carbon (C+6) ion beam accelerated at 15 UD Pelletron produced enlargement in the size of quantum dots revealed by transmission electron microscopic studies.
