Stable self-trapped broadband emission from an organolead halide coordination polymer with strong layer corrugation and high chemical robustness

Abstract

Layered organolead halides are an emerging class of self-trapped emitters, in which the unique corrugated structures are critical to afford out-of-plane distortions for self-trapping. However, the labile corner halide species...

Promoting the formation of metal–carboxylate coordination to modulate the dimensionality of ultrastable lead halide hybrids

“…[30][31][32][33] By employing this general synthetic strategy, we have signicantly advanced the structural integrity and intrinsic stability of lead halide hybrids, primarily attributed to the formation of 3D coordination networks instead of ionically bound structures. [34][35][36] This class of extended coordinative architectures display excellent aqueous stability across a wide pH range and even under boiling conditions. 30,37 However, the vast majority of these structures adopt quasi-2D layered arrangements with tunable layer corrugation and thickness.…”

Zero-dimensional hybrid tin halides with stable broadband light emissions

“…15 Generally, upon photoexcitation, the soft crystal lattice of low-dimensional LDMHs tends to undergo excited-state structural deformation to form self-trapped excitons (STE) due to strong electron-phonon coupling, which further results in broadband emission with a large Stokes shift and wide full width at half maximum (FWHM). 16 Therefore, low-dimensional LDHMs have wide-ranging applications in solid-state white light–emitting diodes with high color rendering index.…”
