Solution Growth

The basic principle behind the solution growth technique involves dissolving a material to be grown in an appropriate solvent and then precipitating the crystals out from the supersaturated solution in a controlled manner. Large crystals can be grown by adjusting the rate of crystallization. Various approaches can be utilized to create the supersaturated solution such as isothermal evaporation of the solvent or a gradual cooling of the saturated solution. At RMD we used both isothermal evaporation and temperature reduction to grow large single crystals of organic scintillators such as DPA.
