The luminescence study of CsPbI3 nanoparticles embedded in Cs4PbI6 crystals.

Description

Cs4PbI6, as a rarely investigated member of the Cs4PbX6 (X is a halogen element) family, has been successfully synthesized at
low temperatures by collaborators from National Taiwan University. Strong red to near-infrared (NIR) emission properties have been detected, and its optical emission centers have been identified to be numerous embedded perovskite-type α-CsPbI3 nanocrystallites (∼5 nm in diameter) based on investigations of temperature- and pressure-dependent photoluminescent properties. A NIR mini-LED for the biological application has been successfully fabricated using as-synthesized Cs4PbI6 crystals. This work provides information for the future development of infrared fluorescent nanoscale perovskite materials.

In that dataset, the scientific article with Supporting Information, raw data of excitation and emission spectra, temperature-dependent and pressure-dependent photoluminescence and decay profiles, and laser power dependent of luminescence are provided.
