Characterization of crystal lattice defects in calcium molybdate single crystals (CaMoO4) by means of X-ray diffraction topography

Calcium molybdate CaMoO4 crystals are perspective materials for many applications in acoustic‐electronics, acoustic‐optics and nonlinear optics. They are also used as laser hosts, scintillators, different kinds of substrates and active elements of ionizing radiation detectors. For all these applicat...

Description
Summary:Calcium molybdate CaMoO4 crystals are perspective materials for many applications in acoustic‐electronics, acoustic‐optics and nonlinear optics. They are also used as laser hosts, scintillators, different kinds of substrates and active elements of ionizing radiation detectors. For all these applications large‐sized single crystals of high structural quality are required. The samples of CaMoO4 crystals have been investigated by means of synchrotron white beam topography, monochromatic beam topography and conventional X‐ray Lang projection topography. The high‐resolution rocking curves have also been taken using synchrotron and conventional arrangements. The topographs showed a rather good crystallographic perfection of the crystals. In particular, they did not reveal any segregation fringes proving high homogeneity of the chemical composition. Relatively high densities (
