Readme file - dataset for the journal article Pump-power-dependence of CsPbBr3-in-Cs4PbBr6 quantum dot color converter

The data in this dataset is used in the Figures 1(c), inset of 1(c) , 1(d), 3(a), 3(b), 4, 5, inset of 5, 6(a), 6(b), 7, 8, 9(a) and 9(b) of the aforementioned research article. The files of the dataset are in csv format and their content is desecribed below. The name of the file relates to the Figure of the article where some of the data is plotted.

Note 1: 'LD' means 'Laser Diode'; 'fwhm' means 'full with at half maximum'; 'BER' means 'Bit Error Rate'

• Fig. 1. (c) - normalized cathodoluminescence (CL) spectra from the surface of the crystal illustrated in Fig. 1 (a)

• Inset of Fig. 1. (c)- CL spectrum corresponding to an area of the crystal illustrated in Fig. 1 (a) with a lower contribution from the peak at 382 nm

• Fig. 1. (d) - PLE spectra of the powder in toluene, centred at 520 nm

• Fig. 3. (a) - Optical power density achieved by the µLED at the focal point vs µLED driving current

• Fig. 3. (b) - Optical power density achieved by the LD at the focal point vs LD driving current

• Fig. 4. - Frequency response of the sample under LD excitation for power densities at the sample of 1.28 and 7.15 kW/cm^2

• Fig. 5. - PL emission of the sample under LD excitation for power densities of 1.3, 2.5, 3.0, 3.9, 5.0, 5.9 and 7.15 kW/cm^2

• Inset of Fig. 5. - Position of the PL peak and fwhm for the different power densities illustrated in Fig. 5

• Fig. 6. (a) - Normalised forward colour converted efficiency for µLED an LD excitation

• Fig. 6. (b) - Log-Log plot of the optical power vs pump power density for µLED and LD excitation; linear fits to the data

• Fig. 7. - Bandwidth (and PL lifetime) for different excitation power densities; lower value corresponds to TCSPC measurement, intermediate values correspond to µLED excitation and higher values correspond to LD excitation

• Fig. 8. - SNR plot for the colour converter under µLED and LD excitation used to determine the bandwidth available for use in communication

• Fig. 9. (a) - BER vs data rate for µLED excitation for the colour converter alone and with blue contribution form the µLED, BER vs data rate for LD excitation for the colour converter alone and with blue contribution from the LD

• Fig. 9. (b) - Illuminance spectrum at the focal point where data rates were collected, corresponding to green contribution form the colour converter and blue contribution from the µLED
