This study presents series of direct band gap Pb-free double perovskite Cs2AgInxBi1-xCl6, Cs2NaxAg1-xInCl6:Bi and Cs2KxAg1-xInCl6:Bi nanocrystal systems [Cs2B′(I)B′′(III)Cl6] synthesised using a colloidal hot-injection route. The structural properties investigated using powder XRD, TEM, solid state...
