Silver gallium sulfide (AgGaS) is a ternary ABX-type semiconductor featuring a direct bandgap and high chemical stability. Structurally resembling diamond, AgGaS has gained considerable attention as a highly promising material for nonlinear optical applications such as second harmonic generation and optical parametric oscillation. In attempts to expand the research scope, on the one hand, AgGaS-derived bulk materials with similar diamond-like configurations have been investigated for the enhancement of nonlinear optics performance, especially the improvement of laser-induced damage thresholds and/or nonlinear coefficients; on the other hand, nanoscale AgGaS and its derivatives have been synthesized with sizes as low as the exciton Bohr radius for the realization of potential applications in the fields of optoelectronics and lighting. This review article focuses on recent advancements and future opportunities in the design of both bulk and nanocrystalline AgGaS and its derivatives, covering structural, electronic, and chemical aspects. By delving into the properties of AgGaS in bulk and nanocrystalline states, this review aims to deepen the understanding of chalcopyrite materials and maximize their utilization in photon conversion and beyond.
硫化银镓（AgGaS）是一种三元ABX型半导体，具有直接带隙和高化学稳定性。AgGaS在结构上类似于金刚石，作为一种极具潜力的材料，在诸如二次谐波产生和光学参量振荡等非线性光学应用中受到了广泛关注。为了扩大研究范围，一方面，人们研究了具有类似类金刚石结构的AgGaS衍生块状材料，以提高其非线性光学性能，特别是提高激光损伤阈值和/或非线性系数；另一方面，已经合成了尺寸低至激子玻尔半径的纳米级AgGaS及其衍生物，以实现其在光电子学和照明领域的潜在应用。这篇综述文章重点关注块状和纳米晶AgGaS及其衍生物设计方面的最新进展和未来机遇，涵盖结构、电子和化学方面。通过深入研究块状和纳米晶态AgGaS的性质，本综述旨在加深对黄铜矿材料的理解，并最大限度地提高其在光子转换及其他领域的利用率。
