The stability of fullerene C-60 and Cu-C-60 nanocomposite thin films are measured by exposing to gamma irradiation at different doses ranging from 25 kGy to 100 kGy. FTIR vibrational spectroscopy shows no effect of gamma irradiation on the fullerene C-60 but gives a C=C vibration at the highest dose of 100 kGy in Cu-C-60 nanocomposite. The Raman spectroscopy was performed at two different wavelengths (325 nm and 532 nm) to know the structural transformation of fullerene and its nanocomposite thin film. At the wavelength of 532 nm, polymerization of fullerene molecules is observed in Cu-C(60 )nanocomposite thin film. UV-visible spectroscopy shows more prominent modes of fullerene C-60 after gamma irradiation. Transmission electron microscopy is used to know the increase in particle size of the nanocomposite thin films. Contact angle measurements are also performed to know the wettability of the gamma irradiated samples. Finally, X-Ray photoelectron spectroscopy is performed to know the elemental state of these samples.

The two-dimensional (2D) heterostructure of black phosphorus (BP)-MXene shows great stability in liquid and gaseous environments. Sensitivity enhancement of a surface plasmon resonance (SPR) sensor utilizing BP and Ti3C2Tx MXene layer is proposed in this work. A CaF2 glass prism is considered as the coupling substrate and 2D Ti3C2Tx MXene as analyte interacting layer. The sensor's performance is demonstrated in terms of sensitivity and figure-of-merit (FOM) values at an operating wavelength of 633 nm. An extremely high angular sensitivity of 322.46 degrees/RIU is obtained, with a significant FOM value of 55.596/RIU (analyte refractive index similar to 1.33) for three -layer BP-Ti3C2Tx MXene monolayer based SPR sensor. Further, the sensing of gaseous analyte using the proposed sensor structure is also explored. This work will open new avenues for application of BP-MXene heterostructure in various optoelectronic devices.
