Abstract:
We discover a rare bluish white-light-emitting Sb3+-based coordination polymer with an unusually large Stokes shift of 230 nm (2.3 eV), ascribed to the assymetric-symmetric coordination shift of the Sb3+ centers. The photoemission renders both a high photoluminescence quantum yield exceeding 30% and a large full width at half maximum of 116 nm. Moreover, the strongly light-emissive material exhibits a linear relationship between the correlated color temperature and the absolute temperature in a wide range (157-457 K), thus presenting the first solid-state luminescent thermometer based on photoemission energy.
