Abstract

A systematic investigation of shock wave-induced defect engineering on optical transport properties of triglycine sulfate (TGS) crystalline material is carried out under shock waves of Mach number 1.7 with a different number of shock pulses. Surface morphological changes and defect concentration are evaluated by the optical microscopic technique. Optical transmission of pre- and postshock wave-treated TGS crystal is analyzed using UV–visible spectrometer over the range between 200 and 800 nm. Unexpectedly, during the shock wave impact conditions, the test crystal exhibits vulnerability due to defects on its surface and it is confirmed by optical micrographs. Optical transmission is continually reduced while the number of shock pulses is increased due to the formation of defects on the surface of the test sample. Followed by the observation of optical transmission, optical constants and band gap energies are also calculated. The obtained results clearly show that surface morphology and optical transport properties of TGS crystal are greatly affected by the impact of shock waves.
