Title: Structure evolution in atoms having phenomenon of electronic transitions

Abstract: In various colloids, thin and thick films, particles and other structure materials where involves bottom-to-up approach in synthesis, it is ambiguous to understand structure evolution. Atoms that are eligible to execute electronic transitions they are entitled to evolve structure. When an atom de-excites where electron excited under shunt energy requires releasing it from inherent binding to nucleus, it generates a photon shape-like Normal distribution, which is being absorbed by adjacent atom at ground state to go into excited state. Instead of absorption, when such photon coincide one giving out by adjacent atom having identical characteristic results into photon couplings between these atoms under energy knot. Structural maturity at primitive cell while achieving certain crystallinity is vital in proceeding evolution. To evolve structure in binary or ternary phase, attained dynamics of atoms along with execution of concurrent electron-dynamics alter depending on the intrinsic nature of constituted atoms. In all sorts of structure evolution, amalgamation of atoms is due to either individually attained dynamics or collectively attained dynamics depending on the characteristic energy photons where binding of atoms takes place at concurrent electron-dynamics under heat energy of suitable merged or squeezed photons. Structure of one-dimension and two-dimension emerge in orientation of attained dynamics of atoms where uni-directional and bi-directional photon couplings take place. In the case of evolving three-dimensional structure, tri-directional photon couplings take place and in amorphous structure non-directional photon couplings take place. This fundamental revolution in the approach to how a particular structure is configured may throws new light on the formation of structure and has serious consequences for materials science.
