“…The T 1 and T 2 energy states describe the lowest and the highest triplet transformation based on the pulse size, wavelength, and pump intensity. The system (S1-S2and T1-T2) are classified as excited-state absorption (ESA), and is related to as reverse saturable absorption (RSA) because its cross-sections are greater than for the ground state. − The measurement begins from − Z where the transmittance is relatively constant ( T = 1). The normalized condition ( T = 1) of Z -scan is exhibited in Figure a.…”

In this work, the green synthesis of highly fluorescent carbon quantum dots (CQDs) with an efficient quantum yield of 17.98% using sugarcane bagasse pulp as the precursor was conducted by a hydrothermal technique. The high-resolution transmission electron microscopy analysis revealed that the CQDs were competently monodispersed with the particle size ranging between 0.75 and 2.75 nm. The structural properties of CQDs were investigated using X-ray diffraction, Fourier transform infrared, and X-ray photoelectron spectroscopy analyses. The UV–visible spectrum showed two absorption peaks due to the aromatic CC transitions of π–π* and CO transitions of n−π*. The fluorescence spectrum of CQDs displayed a strong blue emission. However, the first-ever of its kind, sugarcane industrial solid waste carbon quantum dots caused significant orders to obey the enhancement of the third-order nonlinearity (χ(3)) when compared with other carbon dots (CDs). The calculated nonlinear optical (NLO) parameters such as n 2, β, and χ(3) were 1.012 × 10–8 cm2/W, 2.513 × 10–4, and 3.939 × 10–7 esu, respectively. The figures of merit were evaluated to be W = 6.6661 and T = 0.0132, which greatly fulfilled the optical switching conditions. Besides, the antibacterial activities of CQDs were screened against aquatic Gram-positive (Benthesicymus cereus and Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa, Vibrio cholerae, and Escherichia coli) microbial organisms. Our findings, however, indicate that synergistic sugarcane industrial waste CQDs are promising materials for the functioning of NLO devices, bioimaging, and pharmaceutical applications.

“…The II-VI compound semiconductor (SC) ZnO, a weak ferromagnetic compound, has been studied over the years because of its wide-range applications in optoelectronic and magnetoelectronic devices. 12 Particularly, ZnO is a promising material for diverse applications because of its large exciton binding energy (60 meV) at room temperature and wide bandgap (E g ¼ 3.37 eV) near the UV spectral region. The fabrication of high-quality vertically-grown single-crystalline ZnO nanowires using a simple fabrication has been reported previously.…”
