synthesis, 170 mg of cadmium myristate and 14 mL of 1octadecene (ODE) were mixed in a 100 mL three-neck roundbottom flask and degassed under vacuum at 85 °C for 30 min. Then, the mixture was heated to 250 °C under nitrogen flow. At 250 °C, 12 mg of Se powder well dispersed in 1 mL of ODE with 5 min of sonication was quickly injected (
