Abstract	The photophysical mechanism of ultrabright visible light emission in the zero-dimensional (OD) hybrid organic-inorganic material (HOIM), (DETA)-PbCl5 center dot H2O (DETA = diethylenetriammonium), has been studied. This compound exhibits efficient room-temperature bluish white-light (WL) emission, corroborated by a high photoluminescence quantum yield (PLQY) value of 36.8 % and a Commission Internationale de l'Eclairage (CIE) color coordinates of (0.18, 0.17). Optical investigations reveal that broad-band emission containing multiple emission centers originates from both the fluorescence of the organic molecules DETA and self-trapped excitons within the [Pb2Cl10](6-) inorganic bioctahedral dimers. Furthermore, an enhanced PLQY of up to 40.3% with an adjusted pure WL emission (CIE of (0.33, 0.34)) and a remarkable color rendering index of 90 was achieved through the incorporation of Mn2+ within (DETA)PbCl5 center dot H2O. These findings aid in understanding the photophysical properties of 0D HOIMs and preparation of new families of highly emissive materials for solid-state lighting applications.
