A. Designing organic memory for ROM & RAM applications:
Recently we are working on design and characterization of Resistive Memory devices using organic materials. Such memory devices are expected to be a potential candidate to replace the existing memory based on silicon and will play vital role to realize Organic Electronics. Organic electronics is very promising due to the flexibility, modifiability as well as variety of the available organic molecules. We have already designed resistive memory using several organic molecules and demonstrated their use as both volatile (RAM) and non-volatile (ROM) memory. It has been observed that performance of these memory with respect to data retention, cyclibility, device yield, stability are very good and have every potential for commercial applications.

We are also working on designing various optical sensors. e.g. arsenic sensor and it was found that the deigned sensor give good result while testing the arsenic contaminated water collected from different parts of Tripura. It was found that in Kamalpur there exist arsenic contamination. Our designed alcohol sensor is capable of identifying drunk person just by changing the colour very similar to litmus paper.

D. Design of Nonlinear Optically (NLO) active films
Second-harmonic generation (SHG, also called frequency doubling) is a nonlinear optical process in which two photons with the same frequency interact with a nonlinear material, are “combined”, and generate a new photon with twice the energy of the initial photons (equivalently, twice the frequency and half the wavelength). It is a special case of sum-frequency generation (2 photons), and more generally of harmonic generation. The second-order nonlinear susceptibility of a medium characterizes its tendency to cause SHG. SHG, like other even-order nonlinear optical phenomena, is not allowed in media with inversion symmetry. Second-harmonic generation is used by the laser industry to make green 532 nm lasers from a 1064 nm source, Second-harmonic imaging microscopy, optoelectrnics devices etc. We have demonstrated SHG active thin films (LB) using a thiacyanine derivative which is intrinsically SHG inactive. We also demonstrated the enhancement of stability (SHG signal intensity) by incorporating nano-clay in the thinfilms.

E. Investigations of Fluorescence Resonance Energy Transfer (FRET) & its applications
We are working to identify new FRET molecules, optimise the maximum energy transfer conditions, apply them to design FRET. FRET is a physical dipole–dipole coupling between the excited state of a donor fluorophore and an acceptor chromophore that causes relaxation of the donor to a non-fluorescent ground state, which excites fluorescence in the acceptor. In the process of FRET, initially a donor fluorophore (D) absorbs the energy due to the excitation of incident radiation and transfers the excitation energy to a nearby chromophore, the acceptor (A). FRET is a highly distance dependent phenomenon – 1 to 10 nm distance between donor and acceptor flurophore is crucial for the process to occur. Accordingly FRET phenomenon is used to study molecular scale phenomenon, conformation of macromolecules, optical sensors etc.

Design of Arsenic (V) Sensor: To read the publication – click here
Arsenic (symbol As, atomic number 33) is a group V-A, heavy toxic, ubiquitous element occurring in the atmosphere, soils and rocks, natural waters and organisms. Tripura is highly As prone area.
Recently at Thin Film and Nanoscience Laboratory, Tripura university we have designed a novel Fluorescence Resonance Energy Transfer (FRET)- based ratiometric sensor for detecting arsenic(v) with detection limit 10 ppb.
It was found that the proposed sensor is highly selective with respect to various salts (cations). The proposed method has also been tested using natural lake water and suitable results were obtained with good recovery, ranging between 95.1%–98.6% to the RSD value within range 0.5% −2.6%. The present system has also been tested with real As contaminated water.
