All-inorganic copper-halide perovskites for large-Stokes shift and ten-nanosecond-emission scintillators

Abstract

The recent surge of interest in low-dimensional lead-free copper halide perovskites (CHPs) has driven significant progress in optoelectronics and scintillating materials. However, the development of green-based synthetic routes for CHPs,...

Unveiling the Influence of Organic Chain Length on the Physical Properties of Two-Dimensional Cobalt-Based Hybrid Perovskites

“…The TRPL decay is best-fitted with two exponential decay functions. 36 We note that the first and second components (τ 1 and τ 2 ) are associated with surface and bulk states, respectively, 15,27,28 as LMCT and defect emission are, respectively, too fast (∼tens of ps) 37 and too slow (>1 μs) than both processes. It is widely accepted that the fast average decay time of a hybrid perovskite material is a useful figure of merit for timing applications.…”

“…The measured time-resolved PL (TRPL) decays are listed in Figure . The TRPL decay is best-fitted with two exponential decay functions . We note that the first and second components (τ 1 and τ 2 ) are associated with surface and bulk states, respectively, ,, as LMCT and defect emission are, respectively, too fast (∼tens of ps) and too slow (>1 μs) than both processes.…”
