| Abstract | Summary form only given. We provide a theoretical study of transmittivity of an ultrathin layer (of thickness smaller than an optical wavelength) consisting of oriented organic molecular aggregates (J-aggregates). In spite of the fact that those are complicated systems the excited states of which have the character of Frenkel excitons, an analysis of spectroscopic data of J-aggregates shows, that in a definite area of intensity of the incoming field such films can be modeled as an ensemble of inhomogeneously broadened two-level-systems. An appropriate renormalization of the spontaneous emission rate ensures, that mainly the fewest excitonic state couples to the radiation field. Because of a quite high concentration necessary for the aggregation process itself, in such systems a mechanism of optical bistability, that is due to coupling of the single aggregates via the far-zone field is shown to be possible. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
