Abstract
We have developed a new technique called the slope nucleation method (SNM) for the growth or high-quality 4-dimethylamino-methyl-4-stilbazolium-tosyla te (DAST) crystals. This technique combines the spontaneous nucleation and subsequent growth of a single crystal into one process. The SNM features th e ability to control the nucleation position and the growth orientation of DAST crystals. Many single crystals can be grown simultaneously in one proc ess. X-ray diffraction (XRD) indicates that the SNM is effective for growin g higher-quality DAST crystals as compared to conventional spontaneous nucl eation and the top-seeded solution growth technique. DAST crystals with an XRD rocking curve as narrow as 20.2 arcsec full-width at half maximum (FWHM ) were obtained.
