Abstract
Single crystals of a pure hydrocarbon, 1,3,5-triphenylbenzene, with properties suitable for
high-energy neutron detection were grown from toluene solutions using slow evaporation and
temperature reduction methods with growth rates up to 10 mm/day. Application of the rapid
growth technique developed earlier for growth of large water-soluble crystals shows that crystals
of aromatic compounds can be successfully grown from solutions in large volumes required for
their application as scintillator materials for radiation detection.
1. Introduction
Low-temperature solution growth is the simplest and in many cases the least expensive
method for production of optical crystals. Historically, it was probably the first and the most
widely used technique to produce artificial crystals for many applications, such as mass
crystallization [1], production of pharmaceuticals [2], or growth of relatively small crystals for
crystallographic and other physical studies [3]. However, its use for growth of large,
commercially important single crystals has been very much limited to a few inorganic water-
soluble materials, examples of which include Rochelle salt, triglycine sulphate, or potassium
dihydrogenphosphate (KDP). For organic crystals, not soluble in aqueous solutions, the
preference has been given to alternative methods, among which the Bridgman technique is the
most common. Limited application of solution growth methods to pure organic systems might be1
