Crystal Research Laboratory

In Crystal Research Laboratory (CRL) our main topics of research are Non-linear Optics and Crystal Growth and Nano-Fibers.

Crystal Growth:-

Our lab works for the experimental techniques of Bulk Crystal growth for Non-linear Optical applications. Laboratory is focused specifically on the Growth of semi-organic Non-Linear Optical(NLO) crystals.Non-linear optical crystals are widely used in various applications, such as frequency conversion, electro-optic modulation, and optical switching. This laboratory works slow evaporation technique is one of the most popular methods for growing high-quality non-linear optical crystals. The slow evaporation technique is suitable for growing large, high-quality crystals with a low defect density. This is because the slow evaporation process allows the crystals to grow slowly and uniformly, minimising the formation of defects and impurities in the crystal lattice. These crystals are widely used in a variety of applications, such as telecommunications, laser technology, and medical imaging.

Nano Fibers:-

The NLO crystals are used as frequency doublers and waveguides. Nanofibers are unique for their large surface area to volume ratio, high porosity, appreciable mechanical strength and flexibility in functionalization.

There exist many different methods to make nanofibers, including drawing, electrospinning, self-assembly, template synthesis, and thermal-induced phase separation. In our lab we are synthesizing the nanofibers of NLO crystals by using electrospinning technique. Electrospinning is the most commonly used method to generate nanofibers because of the straightforward setup, the ability to mass-produce continuous nanofibers from various polymers, and the capability to generate ultrathin fibers with controllable diameters, compositions, and orientations. Nanofibers of NLO crystals have many possible technological and commercial applications. They are used in tissue engineering, drug delivery, seed coating material, cancer diagnosis, lithium-air battery, optical sensors, air filtration, redox-flow batteries and composite materials.

The diverse applications of nanofibers of NLO crystals motivates us to explore more in this field.
