This paper describes two cesium cupriferous iodides as nontoxic alternatives to lead containing perovskites. These nanocrystals were synthesized with tailored composition and morphology by a hot-injection colloidal route to produce hexagonal nanoplates (NPs) of blue-emitting Cs3Cu2I5 and nanorods (NRs) of yellow-emitting CsCu2I3. Phase purity was confirmed by Rietveld refinement of X-ray powder diffraction patterns and solid state 133Cs MAS NMR with both compounds exhibiting high thermal stability suitable for optoelectronic technologies. Phase mixing allows linear tuning of Commission Internationale de l’Eclairage (CIE) coordinates from (0.145, 0.055) to (0.418, 0.541) such that a 1:8 molar ratio of Cs3Cu2I5 NPs and CsCu2I3 NRs yields white emission, while the 133Cs MAS NMR demonstrates that these photophysical effects are not attributed to any changes in the Cu oxidation state.<br><br>Data underpinning the related publication is separated into the subdirectories below: X-ray diffraction (XRD) This contains the Origin files containing the figures and raw data for XRD and the raw data and figures of XRD one month later after data was originally taken. Solid State NMR (SSNMR) This contains the raw Bruker TopSpin files for each acquired spectra and calibration. Photoluminescence (PL) This contains two Origin files, G14_123_OA_PL and G19_325_OA_PL, corresponding to each sample that was analysed. These files also contain the raw data acquired in xy format. X-ray photoelectron spectroscopy (XPS) This contains Origin files which include the figures and raw data for each sample. 2020-01-24T00:00:00Z Dataset Dataset 10.1021/acs.chemmater.9b03250 https://figshare.com/articles/dataset/Data_for_Cesium_copper_iodide_tailored_nanoplates_and_nanorods_for_blue_yellow_and_white_emission/33798502 CC BY 4.0
