Fig. 3: Fluorescence monitoring of FTPE crystal structural evolution under high pressure.

Pressure-dependent 3D and 2D fluorescence spectra of FTPE single crystal during the compression process under laser excitation at (a, b) 355 nm, (d, e) 532 nm, and (g, h) 633 nm. Changes in the fluorescence intensity with pressure during compression and decompression processes under laser excitation at (c) 355 nm, (f) 532 nm, and (i) 633 nm. The color in (a, d, g) indicates the magnitude of fluorescence intensity. P+ and P- in (c, f, i) indicate the fluorescence during the compression and decompression, respectively.
