Abstract
Correction for ‘Plasmon enhanced light–matter interaction of rice-like nanorods by a cube-plate nanocavity’ by Hui Zhang et al., Nanoscale Adv., 2022, 4, 1145–1150, DOI: 10.1039/D1NA00777G.
The authors regret that an incorrect method was given for the synthesis of cadmium selenide/cadmium sulfide (CdSe/CdS) nanorods in the Chemical synthesis section.
The correct method is as follows:
In a typical synthesis of cadmium selenide/cadmium sulfide (CdSe/CdS) nanorods (NRs) via the seeded growth method, 78 mg cadmium oxide (CdO, 99.99%), 4.5 g trioctylphosphine oxide (TOPO, 99%) and 0.336 g tetradecylphosphonic acid (TDPA, 97%) were mixed in a 50 mL three-necked flask, heated to 150 °C, and alternately exposed to vacuum or argon gas for an hour. The solution was clear and colorless when the temperature was increased to 300 °C, which indicated the reaction between CdO and TDPA was complete. The temperature was then increased to 325 °C, and 2.25 mL trioctylphosphine (TOP, 97%) was injected into the flask. Subsequently, 0.95 mL Se/TOP stock solution (1 mol L−1) was quickly injected into the flask at 370 °C and maintained for 5 s, 10 s, 20 s, 30 s and 40 s, respectively. In CdS coating, a mixture of 57.9 mg CdO, 81 mg n-hexylphosphonic acid (HPA, 97%), 3 g TOPO and 0.3 g TDPA was heated to 150 °C and evacuated under vacuum or filled with argon gas alternately for 1 hour. 1.5 mL TOP was injected into the solution when the temperature was increased to 300 °C. The mixture of 1.5 mL S/TOP (2 mol L−1) and 0.425 mL synthesized CdSe core solution was injected into the flask quickly and maintained for 8 min at 320 °C. Subsequently, the solution was cooled to room temperature, purified and collected for further characterization. Ag monocrystals were synthesized by a wet chemical method. In short, 1 mol of metal and hydrazine mixture was dissolved in 10 mL of deionized water with magnetic stirring. Subsequently, 10 mL of a 0.03 mol AgNO3 solution was added. Then the microplates solution was washed by ethanol and deionized water four times, and the silver nanocubes were purchased from Nanoseeds.
