Abstract
Morphology-controlled Cs2SbBr6 crystals are synthesized by Bi- and Ag-substitution of the precursor solution. X-ray diffraction (XRD) together with Raman spectroscopy confirms the lattice tilting and symmetry changes with the dominant appearance of higher index facets by Bi substitution. Ag substitution does not induce crystal symmetry changes in the Cs2BBr6 (B = Sb or Bi) phase, but results in highly defective structures hindering the formation of a smooth surface during the crystal growth. Successful substitution of Bi and limited substitution of Ag into Cs2SbBr6 is also confirmed by energy dispersive X-ray spectroscopy (EDX). This research provides design principles and practical examples of how to control the morphology of Cs2SbBr6 crystals with structural defects and multiphase formation.
期刊介绍:
The journal Crystal Research and Technology is a pure online Journal (since 2012).
Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of
-crystal growth techniques and phenomena (including bulk growth, thin films)
-modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals)
-industrial crystallisation
-application of crystals in materials science, electronics, data storage, and optics
-experimental, simulation and theoretical studies of the structural properties of crystals
-crystallographic computing
