Zero-dimensional indium hybrids and modulated photoluminescence by Sb doping

Abstract

Zero-dimensional (0D) indium hybrids have recently explored as promising platforms for use in solid-state lighting owing to their environmental friendliness and stability. Herein, we first designed a novel 0D indium...

Long-Persistent High-Temperature Phosphorescence of Zero-Dimensional Metal Halide Hybrid for Temperature-Sensitive Anticounterfeiting

“…Similar to other 0D MHHs, 45,46 pristine CICH shows a narrow energy dispersion with a band gap of ∼3.09 eV (Figure 6a), indicating the strong localization and large effective mass of carriers. However, different from other reported indirect In-based MHHs, 51,52 CICH exhibits an unusual direct band gap. This difference is attributed to the main contribution of band extrema from organic components in this case rather than the metal halide polyhedron.…”

Efficient triplet energy transfer in a 0D metal halide hybrid with long persistence room temperature phosphorescence for time-resolved anti-counterfeiting

“…This absorption band becomes more prominent concurrent with the appearance of a new band that peaked at 294 nm once the doping level of Sb 3+ is increased to 20%. Consistent with previously reported Sb 3+ -doped MHHs, 11,26,28,45 doping with Sb 3+ often results in new optical properties for hosts without n s 2 metal ions, since the s-electrons of the Sb 3+ dopant could create energy levels within the bandgap of the host, thereby generating new absorption bands at longer wavelengths. 29,45,46 According to previous works, 4,28 these two bands at 294 and 380 nm are assigned to the characteristic 1 S 0 to 1 P 1 and 3 P x transitions of Sb 3+ , respectively.…”

“…1–8 Similar to halide perovskites, 9–15 the photophysical properties of MHHs are mainly determined by the metal and halide components, while the organic component mainly serves as a structural counterion. 16–19 To modulate the optical properties of MHHs, various strategies, such as adopting diverse organic cations 20–23 and doping metal ions, 24–30 have been utilized. Compared to inorganic ions with limited choice and coordinated environments, organic components offer more flexibility in structural manipulation and regulation of optical properties.…”

Achieving Highly Efficient Orange Emission in Tin (IV)‐Based Metal Halides with Outstanding Anti‐Water Stability Through Antimony Doping and Reasonable Structural Modulation

“…Compared to pristine (TBP) 2 SnCl 6 , the absorption spectrum of Sb 3+ -doped (TBP) 2 SnCl 6 exhibits a significant red shift with increasing Sb 3+ doping concentration, indicating that the dopant significantly contributes to the band edge structure of the host matrix (Figure 3), which is consistent with the PLE results. With increasing Sb 3+ content, the absorption coefficient at 310-420 nm was significantly enhanced, which should be assigned to Sb 3+ in the 4d 10 5s 2 5p°configuration, which has a stronger absorption transition than that of Sn 4+ in the 4d 10 5s 0 5p°configuration, [14] thus boosting the efficient orange emission observed in Sb 3+ -doped (TBP) 2 SnCl 6 . Absorption bands at 220-310 and 310-420 nm are clearly observed, which can be attributed to the 1 S 0 -1 P 1 and 1 S 0 -3 P 1 transitions of Sb 3+ , respectively.…”
