Executive Summary : | In recent years, there has been a growing demand for phosphor materials due to their exceptional physiochemical, electronic, and optical properties. These materials find applications in various industries such as commercial lighting, medical diagnostics, and biochemical probes. To date, a considerable array of fluorescent materials has been identified, encompassing quantum dots (QDs), dyes, lanthanide (Ln)-based phosphor materials, and metal-organic frameworks (MOFs). However, these materials continue to exhibit certain constraints. The rapid photobleaching and low chemical stability exhibited by these dyes impede their ability to maintain fluorescence over an extended period of time. The primary origin of quantum dot (QD) synthesis lies in the utilization of heavy metal ions, which unfortunately possess inherent toxicity, surface imperfections, and environmental hazards that impose limitations on their practical applications. Lanthanide-based fluorescence exhibits a relatively low quantum yield and typically necessitates the presence of a host molecule or atom to facilitate energy transfer. In this proposal, we aim to advance the field by designing novel metal-organic frameworks (MOFs) incorporating lanthanide elements (Ln) for the production of luminescent thin films. These films can be subsequently enhanced to cater to a wide range of applications, including sensing, biomedical research, and fields. Additionally presents a comprehensive investigation into the structural, optical, and electronic characteristics of luminescent thin films that have been developed, along with an analysis of methods for optimizing their properties. Moreover, we will integrate luminescent thin films in order to develop them as portable devices for sensing and optoelectronic applications.
Further, this project proposal aims to generate novel Ln-MOF thin films to provide a stable platform with features that overcome the limitations associated with powder- and solution-based Ln-MOF sensors for the sensing of biomolecules and biomarkers. Further, the integration of thin film with easily accessible devices (smartphone-based, UV lamp, bare eye) to get a fast response and an easily assessable and handy device for diagnostics that can be utilized by medical science and society to reduce cost, accessibility, and speed of response. In this research work, researchers also create a successful outcome to generate enervative, patentable intellectual property and developed it as a product for commercial application. |
