“…Altogether these findings suggest that “orthorhombic” subdomains may form in our NCs, giving rise to a multiply twinned structure, as already theoretically proposed and experimentally confirmed by optical microscopy and 133 Cs NMR studies on bulk CsPbCl 3 . 60 62 …”

“…T 2 times for bulk material above 273 K could not be determined, presumably due to the ferroelastic phase transitions of bulk CsPbCl 3 which occur around room temperature (RT) and might impede the detection of the NMR signal. 25 , 54 56 In NCs, these phase transitions may be absent or occur only at higher temperatures, since the 35 Cl NMR spectra could be acquired without difficulties at RT.…”

“…), and NQR, NMR, and EPR spectra. [4][5][6][7] It has been found that first order phase transitions take place at T c1 and T c3 and second order phase transitions, at T c2 . An analysis of EPR spectra measured at different temperatures shows that, besides these phase transitions, CsPbCl 3 undergoes phase transitions at 194 and 176 K. 7 Studies of the luminescence spectrum at temperatures of 4-300 K also reveal a low-temperature phase transition at 176 K: a new luminescence band appears below this temperature and a singularity is observed in the temperature dependence of the steepness of the Urbach absorption edge.…”
