Over the last twenty-five years, the demand for electricity has skyrocketed dramatically, and the country is facing a terrible power reliability situation. The illumination of highways and roads is the biggest challenges faced by the government. Secondly, almost one-fifth of India’s rural households still remain in acute darkness. There is a huge gap between the electricity demand and the electricity being produced in the country. The current advancement in technology has been providing various solutions for the existing problem. On that context, cement being an omnipresent material, can be made photo luminescent. Photo luminescence is the light emission from any form of matter, initiated by photo excitation. This project presents an investigation on the introduction of photo luminescent property in concrete. The proposed concept is to induce light emitting pigments in glass so as to produce glow in the dark concrete. Photo luminescent pigments incorporated in the concrete, consist of rare alkaline earth elements from the lanthanide series and hence are proven to be inert, ensuring minimal harm to the environment. The resulting concrete material is found to have considerable compressive strength and possess light emitting properties. Implementing photo luminescence induced concrete has a high potential to make a valuable contribution to sustainable development in the future.
