“…The main properties of SbSI have been reviewed in a few monographs [23][24][25][26][27]. However, the properties of these materials are still investigated [28][29][30][31]. The properties of the 1D SbSI remain little known.…”

“…4,5 It is highly anisotropic orthorhombic phase structure which consists of innite ribbon-like SbSI polar chains linked together and extend along c-axis, making its crystal preferentially to grow into one-dimensional (1D) structure anisotropically. 6 Being a promising material with potential applications, the 1D SbSI crystals with various dimensions have been synthesized in different ways such as vapor deposition, sonochemical and hydrothermal routes. 4,[7][8][9][10][11][12] As noted, chemical vapor deposition (CVD) is available for the growth of poly-crystalline bulk from their corresponding elements at temperature over 600 C, 7 and sonochemical process can produce SbSI at a relative low temperature below 100 C while the surface of the as-grown nanocrystals oen shows an amorphous layer.…”

A new rapid and low temperature hydrothermal process has been developed to synthesize one-dimensional (1D) single-crystalline SbSI microrods at 160 C for 4 h with high quality. Moreover, a first individual SbSI microrod based photodetector equipped with indium-tinoxide (ITO) electrodes is constructed on a SiO 2 /Si substrate. The resulting device displays a remarkable response to visible light with an on-off ratio up to 727, a detectivity of 2.3 Â 10 8 Jones, a noise equivalent power of 1.7 Â 10 À10 W/Hz 1/2 and fast response/recovery times (<0.3 s).

“…SbSI is one of the most interesting members of ternary chalcohalide materials with indirect and direct band gaps . It has a highly anisotropic orthorhombic phase structure, which consists of infinite ribbon-like SbSI polar chains linked together along the c -axis, making its crystal preferentially to grow into a one-dimensional structure anisotropically . Its band structure suggests that the fundamental gap is indirect, that is, Γ 6 → S 1 at 1.82 eV, and the smallest direct gap occurs at Γ with an energy of 2.08 eV .…”

Based on its excellent visible light absorption and photoelectric response capabilities, SbSI has attracted significant research attention for a wide range of applications. Despite the fact that interesting physical properties can be induced from the sophisticated band structures of SbSI, that is, either with direct or indirect band gaps, its nonlinear optical (NLO) properties are not yet fully explored. In the present work, the NLO response of SbSI nanorods is investigated by the combination of open-aperture (OA) Z-scan, pump−probe, and spatial self-phase modulation (SSPM). It is found that the synthesized SbSI nanorods possess a relatively large nonlinear absorption coefficient and a small saturable optical intensity at a wavelength of 400 nm, compared to those of other materials. More importantly, the OA Z-scan experiments suggest that the direct band gap of SbSI plays a dominant role on the NLO effects, which is further verified by the SSPM experiments. The present work suggests that the SbSI nanorods may have great potentials for optical switches and saturable absorbers.
