Abstract

In the present work we report the Laser Induced Fluorescence (LIF), SEM and Iridescent Patterns of molluscan Shells. The intensity distribution patterns of different iridescent patterns are worked out with the help of software (Image J). The iridescent colours of shells are ascribed to diffraction and also due to laminated structure. Laser induced fluorescence spectra are recorded for a specimen in a organic solvent, using blue, green and red diode laser. Nine fluorescence peaks at 470, 450-600, 680, 718, 720, 734, 756, 820 and 840 nm are observed and their assignments have been proposed. The SEM patterns of a powered specimen are analysed.
