The luminescence of single crystals of (TBA)PbCl, (TBA)SbCl, (TBA)BiCl and (TBA)SnCl·2EtOH (TBA = tetrabutylammonium, EtOH = Ethanol) synthsized were assigned distinctively to the centres of self-trapped excitons (STEs), TBA, TBA and co-emission of STEs and TBA. This work demonstrates that organic cations without benzene or aromatic rings can also be used as the sole luminescence centres for metal halides.
