摘要：
Bulk single crystals of pure and amaranth doped KDP were grown using point seed technique. Effect of amaranth doping on KDP crystals was analyzed using powder XRD, thermal analysis (TG/DTA), dielectric, photoconductivity and etching studies. The phase purity and crystallinity of pure and dye doped crystals were confirmed by powder X-ray diffraction analysis. It is observed from TG-DTA analysis that the decomposition point decreased while doping with amaranth. Dielectric constant and loss increases with increasing temperatures. The photoconductivity decreases with the increase of amaranth concentration. (C) 2016 Elsevier B.V. All rights reserved.
