The synthesis of hollow CdS nanospheres packed with square subunits

Abstract Hollow CdS nanospheres packed with square subunits were fabricated via microwave irradiation and pentaerythriol. The products were characterized with XRD, TEM, HRTEM, EDX and UV–vis spectrum. The results indicate that pentaerythriol is necessary in the formation of square subunits with high degree of crystallinity. A possible growth mechanism was proposed.
