Dhanbad: A research group comprising Prof J Manam, Prof S K Sharma and Dr. Sourav Das of IIT (ISM)’s Department of Physics, has developed advanced luminescent materials for defence and security applications.

The Rs 37 lakh project, which has been on for three years has resulted in the development of a substance that can be used for tagging, tracking and locating defence applications.


This material exhibits – ‘Long persistent luminescence’, a phenomenon in which material exhibits light after being exposed to solar light for a long time.

The IIT (ISM) during the first 2 ½ years of research which began on from March 2019 developed long persistent phosphor material which gives emission to the Near Infrared Region (NIR)

The material can be excited by the solar radiation during the day time and NIR radiation can be observed by night vision monocular for 24 hours.

Talking to The Telegraph Online today, Sourav Das said, “We began the project during March last year and have already prepared the material at the laboratory level and its application has also been made for which publication has already been made in a reputed journal.”

He added, “This material has been developed for the first time in India. It took us 2 ½ years of the allotted three years to develop this material. Despite the institute remaining closed due to the pandemic, we have been able to meet the target.” This material is akin to the material used in the glowing duck, a toy for the kids.
