| Abstract | In this study, optical stop band of three-dimensional silica shell photonic crystals is tuned by adjusting inner diameter and shell thickness of hollow silica spheres. The silica shell photonic crystals are fabricated by sintering crystalline arrays, which are assembled from polystyrene/silica core–shell spheres by an improved vertical deposition method. The inner diameter and the shell thickness are controlled by diameter of polystyrene spheres and concentration of tetraethoxysilane. The results of transmission spectra show that there is an evident red shift of optical stop band as the inner diameter and the shell thickness increase. The red shift of optical stop band is due to variations in the inter-planar spacing and the effective refractive index of silica shell photonic crystals, which result from the variations of the inner diameter and the shell thickness of hollow silica spheres. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
