| Abstract: | Cadmium selenide (CdSe) hollow nanospheres (approximately 40–50 nm) have been successfully synthesized by γ-irradiating polyacrylamide (PAM) hydrogel template which contains CdCl2 and Na2SeO3 aqueous solution at room temperature. The nanospheres were characterized by energy dispersive spectrum (EDS), field emission scanning electron micrograph (FESEM), transmission electron microscopy (TEM) and high-resolution transmission electron micrograph (HRTEM), respectively. EDS showed that nanospheres were composed of Cd and Se (atomic ratio, 1.15:1). A possible formation mechanism of CdSe hollow nanospheres through two-steps was presented. |
