A hybrid material based on a 1D copper chloride perovskite network with hexahydro-1,4-diazepine, (C5H14N2)[CuCl4], was grown at room temperature by slow evaporation. This compound crystallizes in the monoclinic space group...

A 1-D Cu(ii)-based perovskite (C5H8N3)[CuCl3], with gap energy “Eg” of 2.21 eV, has been successfully investigated as a good UV–Vis–NIR absorber. The magnetic analysis suggests that this material can be described by the model of S = 1/2 AFM dimers.

Under sub-gap excitation, the materials exhibit white light emission (WLE) that originates from the STE within CdBr4 and the organic phosphorescence (for CdACP) and fluorescence (for CdODA). Under excitation above the gap the WLE is purely organic.

Newly, room temperature phosphorescence (RTP) in 2D hybrid perovskites has been proved due to the energy transfer from inorganic sheets to the conjugated organic cations harnessing the triplet states. So...

The synthesized 1D-perovskite-type (C6H7NBr)3[CdBr5] shows a broad-band white light emission with an extra-high CRI of 98 and chromaticity coordinates (0.30, 0.32).
