TL;DR: The effect of the nanostructure on the UV-vis absorption and luminescence of the antimonide nanoparticles has been studied in this paper, where NiSb nanoparticles of diameter about 10-40 nm and FeSb2 nanorods of 6 nm wide and 15-30 nm long were synthesized by using SDS as surfactant.
Abstract: Transition metal antimonide nanoparticles, NiSb and FeSb2, were synthesized by solvothermal method with the inclusion of various kinds of additives. X-ray diffraction (XRD) analysis confirmed the formation of hexagonal NiSb and orthorhombic FeSb2. NiSb nanoparticles of diameter about 10-40 nm and FeSb2 nanorods of 6 nm wide and 15-30 nm long were synthesized with the addition of SDS as surfactant. The structural analysis by transmission electron microscopy (TEM) also revealed the formation of transition metal antimonide nanoparticles with high purity and better crystallinity. The effect of the nanostructure on the UV-vis absorption and luminescence of the antimonide nanoparticles has been studied. The nanosize transition metal antimonides such as NiSb and FeSb2 have applications as inclusion materials in CoSb3 skutterudites in developing thermoelectric devices with better energy conversion efficiency.

TL;DR: In this article, the growth process of the bi-alkali antimonide material K2CsSb was investigated using X-ray diffraction and structural and chemical changes were investigated.
Abstract: Bi-alkali antimonide photocathodes are one of the best known sources of electrons for high current and/or high bunch charge applications like Energy Recovery Linacs or Free Electron Lasers. Despite their high quantum efficiency in visible light and low intrinsic emittance, the surface roughness of these photocathodes prohibits their use as low emittance cathodes in high accelerating gradient superconducting and normal conducting radio frequency photoguns and limits the minimum possible intrinsic emittance near the threshold. Also, the growth process for these materials is largely based on recipes obtained by trial and error and is very unreliable. In this paper, using X-ray diffraction, we investigate the different structural and chemical changes that take place during the growth process of the bi-alkali antimonide material K2CsSb. Our measurements give us a deeper understanding of the growth process of alkali-antimonide photocathodes allowing us to optimize it with the goal of minimizing the surface roughness to preserve the intrinsic emittance at high electric fields and increasing its reproducibility.
