Resulting nano-sized colloids have been characterized by FT-IR spectroscopy, UV-Visible spectroscopy, X-ray diffraction, and Transmission Electron Microscopy (TEM). Very strong surface Plasmon resonance peak at 410 nm in the UV-Visible is a direct evidence of formation of nano-sized silver colloids. XRD Diffraction pattern reveals the formation of cubic structured crystals.Transmission Electron Microscopy (TEM) confirms average diameter of silver nanoparticles as 9 nm. The non-linear refractive index ( 2) were calculated by Z-Scan technique using CW He-Ne laser (λ=632 nm)and are obtained as high as 3.353 x 10 4 cm 2 /W,8.697 x 10 4 cm 2 /W, and 9.469 x 10 -4 cm 2 /W for 1 wt%,2 wt% and 5wt% of PVP ...

The differential thermal analysis shows the material melts at 898C. The synthesized material exhibits monoclinic crystal structure with the space group C2, which has been confirmed from powder X-ray diffraction study. The second harmonic generation (SHG) in the powder sample was examined by using Nd:YAG laser with a fundamental wavelength of 1064 nm. The test confirms the SHG by the synthesized material. From the Fourier transform infrared analysis, BO3 and BO4 are the ionic groups exist in the materials which are responsible to produce NLO phenomenon in the prepare samples.

A simple cladding modification technique was used to construct the sensor by uncladding the small portion from optical fiber. Further bare core was decorated by supportive porous, chemically and optically sensitive matrix material polyaniline (PANI) as an active cladding for enzyme residency. Enzyme-urease (Urs) was cross-linked on the active cladding region via glutaraldehyde solution. Confirmation of the prepared PANI in proper form determined by ultraviolet-visible and Fourier transform infrared spectroscopic techniques. X-ray diffraction technique was employed for nature and compatibility examination of PANI. Sensor parameters such as sensitivity, selectivity, stability and lower detection limit have been analyzed by absorption variation study in evanescent wave field. The response of prepared sensor was studied towards urea in the wide concentration range 100 nM–100 mM and confirmed its lowest detection limit as 100 nM. The stability of sensor was found 28 days with little variation in response. The fabricated sensor has not shown any response towards interference species like glucose, ascorbic acid, l -alanine, l -arginine and their combination with urea solution and hence found selective for urea solution only.

The incorporation of glycine in BTCF crystal was confirmed by Fourier transform infrared (FTIR) analysis. The UV-visible transmittance spectrum of pure and doped BTCF crystals was recorded to comparatively analyse the optical transparency, optical bandgap and other optical constants. The third-order non-linear behaviour of grown crystals has been investigated at 632?8 nm using Z-scan technique, and vital third-order non-linear optical (NLO) constants were calculated. The second harmonic generation (SHG) efficiency of doped BTCF crystal is found to be 2?15 times that of KDP material. The fluorescence studies of doped BTCF crystal confirmed the red colour emission in the visible region. The thermal stability of grown crystals was determined by means of thermogravimetric analysis (TGA). The dielectric measurement studies were performed at room temperature. The surface morphology of doped BTCF crystal was analysed by scanning electron microscopy (SEM) technique.

The negative photoconducting nature of LAZTC crystal has been investigated by means of photoconductivity studies. Thermal stability of LAZTC crystal was evaluated by thermogravimetric and differential thermal analysis. The dielectric measurements confirmed the lower dielectric characteristics of LAZTC crystal.
