Group Vision
Transformation of material from bulk to nano size results in modified electrical, optical, magnetic and chemical properties. These properties can be used to solve problems in the area of health, energy, security and environment. Our group focuses on some of the intricate problems in these areas and intend to solve them by designing new materials using various synthetic routes. Further, our group is involved in developing a deep insight into the mass-transport problem of nanomaterials into biological systems and formulate a mathematical model which can provide reasonable explanation to the problem. Also, through our understanding in the area of Chemical Engineering, Chemistry, Physics and Mathematics, we hope to design new nanosystems capable of detecting communicable and non-communicable diseases besides heavy metal, metalloids and radioactive materials as well. Our group is also actively participating in the development new catalyst for water splitting, hydrogen generation, CO2 sequestration, and synthesis of new materials.

Design and Development of Non-Linear Optical Nanomaterials

Non-linear luminescent nanomaterials based on NaYF4 host-lattice are one of the most efficient upconverters of multiple low energy photons to a high energy photons. These upconverting nanomaterial, display near infrared excitation, narrow emission and excitation band, environment invariant emissions, and no photobleaching, making them suitable for application in the area of nanomedicine, imaging, biosensing, photocatalysis, energy generation, displays and opto-bi-functional devices. Despite great potential, their applicability remains limited due to restricted colour availability, small extinction coefficient and low quantum yield. Our group focuses on the development of new synthetic routes to produce multicolour, multimodal upconverting materials having improved quantum yield and use in the area of energy generation, photocatalysis, heavy metal and arsenic detection.

New Material and Devices

Ubiquitous arsenic presences in the earth crust and ground water has impending effect on global health, almost affecting 144 million population. Despite these issues, development of new optical materials that can facilitate simple, easy, reliable, sensitive and selective detection of As3+ remained limited. Our research group has been able to successfully develop new optically active 2-D materials that can detect arsenite (As3+) at 12.5 parts per trillion levels with high accuracy (99% spike recovery). We envision its use in miniaturized optical system as pocket carrying devices.
