supporting data for " The Role of Organic Spacer Cations on the Structural and Optoelectronic Properties of Two-Dimensional Halide Perovskites"

The data I have uploaded primarily represents the material system that I researched in my MPhil thesis. It mainly includes Raman spectroscopy data, which was used to characterize the inorganic structural distortion of the perovskite that I synthesized.

 Additionally, there are PL emission data, which characterize the luminescence properties of the synthesized samples, reflecting their bandgap and exciton properties. 

There is also TCSPC data, which characterizes the radiation path of different samples and reflects their exciton radiation recombination lifetime.
