Growth and characterization of benzil single crystals using nanotranslation by the modified vertical Bridgman technique

Abstract

Benzil single crystals have been grown by the modified vertical Bridgman technique using the double wall ampoule with nanotranslation for the first time. The characterization studies of benzil crystals grown by both single and double wall ampoules were analyzed. The grown benzil crystal was confirmed by single crystal and powder X-ray diffraction analyses. Fourier transform infrared analysis confirms the functional groups of the grown benzil. High resolution X-ray diffraction analysis indicates the crystalline perfection of the grown crystals. The UV-Vis-NIR studies show that the grown benzil crystals cutoff wavelength is around 434 nm. The green emission of the grown benzil was identified by photoluminescence studies. The thermal property of the grown benzil was studied by thermogravimetric and differential thermal analyses. The dielectric measurements of benzil crystals were carried out with different frequencies and temperatures and the results indicate an increase in dielectric and conductivity parameters with the increase of temperature at all frequencies. The second harmonic conversion efficiency of the grown benzil was determined.

Effect of glycine addition on the structural, thermal, optical, mechanical and electrical properties of Sr (HCOO)2·2H2O crystals

“…Nonlinear optical (NLO) materials with high optical nonlinearity have been the subject of intense research in recent years [1][2][3]. The development of photonic and optoelectronic technology heavily depends on new semi-organic NLO materials due to their high optical nonlinearity, thermal stability, chemical flexibility of ions and excellent optical transmittance in the UV-visible regions [4][5][6][7][8][9][10].…”

The Ampoule Method: A Pathway towards Controllable Synthesis of Electrocatalysts for Water Electrolysis

“…Both organic and inorganic single crystals can be prepared via the ampoule method. Typical organic single crystals include benzil ( Figure 4a) [35] and benzimidazole [36] crystals for optical devices. Inorganic complex single crystals, such as magnetic PrCo2 [37] and superconducting Ba1-xRbxFe2As2, [38] are synthesized via this method.…”
