(a)Pressure-dependent PL emissions of 4CzTPN. Insets illustrate the corresponding PL micrographs with increasing pressure. (b) Pressure-dependent emission wavelengths of 4CzTPN. Green line represents linear fittings of the data to achieve pressure coefficients of emission wavelengths. (c) UV–vis spectra of 4CzTPN under high pressure. Insets illustrate the corresponding sample micrographs with increasing pressure. (d) PL emissions of 4CzTPN upon grinding at ambient conditions. (e) Pressure-dependent PL emissions of 4CzTPN powder. Insets illustrate the corresponding PL micrographs with increasing pressure. (f) Schematic illustration of the in-situ high pressure PL measurements.
