Experimental Set up for Sankaranarayanan–Ramasamy (SR) method-cfm...
Sankaranarayanan–Ramasamy (SR) method is used to grow bulk crystals with specific orientation. This SR method is a suitable method to effectively control the orientation of molecules during the bulk crystal growth from solution at room temperature with 100% solute to crystal conversion efficiency. Unidirectional crystals are very important for the preparation of functional crystals. For example, the conversion efficiency of second harmonic generation is always highest along the phase-match direction for nonlinear optical crystals, in such cases unidirectional crystal growth method is the most suitable to grow bulk sized crystals along that particular direction. The experimental setup consists of two ring heaters, transparent glass tubes made by borosilicate glass and seed mounting pad. The ring heaters are positioned in the top and bottom of the ampoule. The heaters are connected to a dual channel temperature controller which maintains constant temperature. The entire setup is kept in a water bath. The experimental setup was placed in a dust-free hood.
