“…The details of these modifications, as well as major procedures and requirements of material purity were described in a recent publication [9]. By analogy with the rapid growth of KDP [22], in the first experiments a small "point" seed glued in the centre of the platform crystal-holder with vertical position of the monoclinic b-axis was used.…”

“…The platform was introduced into the solution heated above the saturation temperature that then was decreased to start growth of fully faceted crystals. It was very soon established that to obtain such crystals without visible solution inclusions was possible only at extremely slow growth rates below ~1 mm/day }faces; (c) 10 cm tall crystal grown without {11 1 } faces, growth of which was restricted by the platform design [9]. grown crystals unsuitable for any optical tests or scintillation applications.…”

“…Recently Carman et al [9] and Zaitseva et al [10] showed that high-optical quality crystals of stilbene can be grown to a 10-cm scale from solution. Some current and future applications may require larger size and quantity of crystals, production of which can be a complicated task without detailed knowledge of the growth mechanisms and structure, to avoid formation of defects harmful for the final application.…”

AbstractSingle crystals of trans-stilbene, C 14 H 12, with properties suitable for high-energy neutron detection were grown from solution in anisole and toluene by the temperature reduction method with growth rates up to 6 mm/day. From these crystals, slices of appropriate orientation and thickness of 2 -4 mm were cut and studied by X-ray diffraction topography applying the Lang method using CuKα radiation. The topographs exhibit growth defects such as liquid inclusions, dislocations, striations, and faulty growth-sector boundaries. These defects occur in the same typical arrangements and geometries as is observed in all kinds of crystals grown on habit faces from solution. Besides growth dislocations originating from inclusions and propagating with the growth front, many plastic glide dislocations in the shape of loops or half-loops emitted from inclusions by stress relaxation are observed. The glide system underlying this plasticity is discussed.

“…The possibility of utilizing solution growth techniques [32], especially if crystals can be grown from water [33], is an additional advantage that simplifies potential production of large inexpensive crystals, making Li-3-PSA a promising material for future development. 252 Cf PSD measured in a Li-3-PSA single crystal with 9 mm HDPE moderation; inset shows a picture of the $ 3 cm size crystal used for the measurements; (b) "triple" PSD patterns calculated for the near-thermal-neutron-spot energy range.…”

Organic single crystals (OSCs) have ideal qualities (well defi ned structure and\ud morphology, lack of grain boundaries, high purity, 3D long range order, good\ud electronic transport properties) for several technological applications, in particular\ud as key components for electronic devices. It is only recently that OSCs\ud have been considered as ionizing radiation detectors, and the latest developments\ud in this fi eld are here reported. In the fi rst section, various methods for\ud OSC growth are described, with emphasis on cost-effective, solution-based\ud approaches capable of delivering large volume, well performing crystals. The\ud second section is focused on the use of solution-grown OSCs as scintillators\ud (i.e., as high energy photon to UV–vis photon conversion), highlighting\ud the ability of cm-scale OSCs to effectively detect neutrons and to carry out\ud neutrons-gamma pulse-shape discrimination tasks. Finally, the third section\ud describes the use of semiconducting, solution-grown OSCs as effective\ud solid state direct detectors (i.e., directly converting high energy photons into\ud charge carriers), evidencing extremely promising performances in terms of\ud operability in environmental conditions (i.e., no need for encapsulation),\ud radiation hardness, linear response and low operating voltage
