DATA & FILE OVERVIEW

1. File List: 
Dataset.opj containing 
FFTmap : Fast fourier transformed 2D vibrational map
FFTpower : The power of dominant vibrational modes as a function of wavelengths
FFTspectra : Fast fourier transformed spectra averaged in two wavelength ranges (560-600nm and 620-880 nm) in comparison with Raman spectra (excitation wavelength 633nm)
fsTA : Femtosecond transient absorption map of two 2D perovskites
FWHM : FWHM of the PL emission as a function of temperature
LowTPL : PL spectra that were collected below room temperature
PDS : Data of the photothermal deflection spectroscopy measurements
RoomTAbsPL : Absorption and PL spectra of two 2D perovskites at room temperature



METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
Link of the description: https://pubs.acs.org/doi/10.1021/acsnano.7b03984

2. Methods for processing the data: 
FFT data were processed by performing FFT function in OriginPro on fs-TA data
FWHM were determined through fitting of the PL spectra using OriginPro

3. Instrument- or software-specific information needed to interpret the data: OriginPro

5. Environmental/experimental conditions: Despite LowTPL that were measured below room temperature, all other data were generated on encapsulated samples at ambient conditions.

6. Describe any quality-assurance procedures performed on the data: Blank quartz samples were used as references.

7. People involved with sample collection, processing, analysis and/or submission: 
Ni, L.; Huynh, U.; Cheminal, A.; Thomas, T.; Sadhanala, A.; Shivanna, R.; Hinrichsen, T.; Ahmad, S.; Rao, A.
