Investigation of emission properties of doped aromatic derivative organic semiconductor crystals

Effect of heavy ions irradiation on the properties of benzil crystals

“…The melt growth could be used because benzil is characterized by good thermal stability at the melting point . The experimental set‐up (figure a) was realized by modifying the B‐S vertical configuration for assuring steep gradients at the melt‐crystal interface (12 °C/cm) and low moving speed of the growth interface (0.7 mm/h). These conditions must be satisfied to compensate the supercooling and low thermal conductivity characterizing the organic compounds with big molecules, such as benzil.…”

“…The interest to investigate the effect of radiation on the properties of organic crystalline materials can be justified, in the first place, by their potential application in detection systems, including sensors working in hazardous environment. The organic fluorescent compounds seem attractive for ionizing radiation detection because the π‐electrons system favors the fluorescence and/or intermolecular energy transfer …”

“…In particular, the interest in studying the crystal of benzil is justified by its behavior similar to the inorganic wide‐gap semiconductors and its isomorphism with α‐quartz being known as “organic quartz”. Just like quartz used as matrix for metallic microstructures, benzil can be use as matrix for composite materials . The particularities of its molecular and crystalline structure favor the generation of free spaces, having a diameter of 2.9 Å, adequate for the inclusion of foreign atoms and molecules, or for the development of specific internal microstructures of a different phase.…”

The effect of succinic acid on the physico-chemical characterization studies of benzil NLO single crystal

“…It has also been elucidated that on doping with Succinic acid, the SHG efficiency has been considerably increased. Moreover dopants are playing a major role in enhancing and altering the properties of organic single crystals [19][20][21].…”

Heat transfer process during the crystallization of benzil grown by the Bridgman–Stockbarger method

“…Benzil is an aromatic compound, which in solid-state could have potential applications in nonlinear optics because of the: (i) high nonlinear coefficient, (ii) large birefringence, (iii) high damage threshold and (iv) large transparency domain [5,6].…”
