Fig. 1: RD-ZIF-8 templated one-pot synthesis of gold semi-shells.

A Schematic of semi-shell synthesis; B Extinction spectra and C FESEM images of semi-shells prepared with (i) 0 mg mL−1, (ii)−0.5 mg mL−1, (iii)−1 mg mL−1, (iv)−2 mg mL−1 of ZIF-8. Inset in B shows a shift in λmax and color change of reaction mixture from light ruby red to cyan in the presence of ZIF-8; D Elemental mapping of SS for gold and zinc.
