Fig. 4: Power-dependent photoluminescence properties.

From: Manipulation of parity and polarization through structural distortion in light-emitting halide double perovskites

Fig. 4

a Power-dependent photoluminescence spectra of Bi0.10In0.90 compound. The photon flux (380 nm) is varied from 0.2 lux to 569.2 lux. The inset shows the photoluminescence at low photon fluxes (0.2–4.6 lux). b The integrated intensity under the photoluminescence curve shown in Fig. 4a is plotted as a function of incident photon flux.
