Comments on the paper: Structural, optical properties and effect of amino acid on growth of KDP crystals

Abstract

The L-arginine mixed potassium dihydrogenphosphate (KDP) crystal reported by Saravanan et al Indian J Pure App Phys 51 (2013) 254, is a dubious crystal. The reported unit cell parameters contradict the definition of the tetragonal crystal system.
