Abstract

Growth of bulk single crystal of 4-Aminobenzophenone (4 ABP) from the vertical dynamic gradient freeze (VDGF) setup designed with eight zone furnace was investigated. The experimental parameters for the growth of 4-ABP single crystal with respect to the design of VDGF setup are discussed. The eight zones were used to generate multiple temperature gradients over the furnace, and video imaging system helped to capture the real time growth and solid liquid interface. 4-ABP single crystal with the size of 18 mm diameter and 40 mm length was grown from this investigation. Structural and optical quality of grown crystal was examined by high resolution X-ray diffraction and UV -visible spectral analysis, respectively and the blue emission was also confirmed from the photoluminescence spectrum. Microharclness number of the crystal was estimated aL different loads using Vickers microhardness Lester. The size and quality of single crystal grown from the present investigation are compared with the vertical Bridgman grown 4-ABP.
