This book is the description about the surface plasmon resonance (SPR) in alkali halide in thin films state and how the formation of Cesium nano-rod in Cesium Hailde depends on residual stress and diffusion of vacancy. and also, how the variation of grain size changes the basic parameters of the material. This book is intended for researchers pursuing research in material science and will be helpful to understand the SPR in thin films state.
