System description
Dimensionality: 2D n: 1
Sample type: film

Starting materials: (PMA)2PbBr4 crystals, DMF, glass substrates

Product: Thin film on glass

Description: Dissolve the 2D single crystals into DMF at a concentration 6%∼10% relative to the total weight. Spin-coat at 3000 rpm for 30 s on glass substrates. Anneal in air at 100 °C for 10 min before measurement.

Method: UV-Vis absorption

Description: Optical absorption spectra were obtained using a Shimadzu UV-3600 spectrophotometer.
