Starting materials: (NMA)2PbCl4 crystals, DMF, quartz substrates

Product: Thin film on quartz

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 quartz substrates. Anneal in air at 100 °C for 10 min before measurement.

Method: Photoluminescence

Description: The photoluminescence spectra were measured using a Horiba-Jobi-Yvon LabRAM ARAMIS system, with a 325 nm He-Cd laser excitation. The laser beam was collimated and focused through a 40X UV objective onto the sample surface at room temperature. Refer to figure 5.
