A facile and eco‐friendly hydrothermal method was used to prepare carbon quantum dots (CQDs) using orange waste peels. The synthesized CQDs were well dispersed and the average diameter was 2.9 ± 0.5 nm. Functional group identification of the CQDs was confirmed by Fourier transform infrared spectrum analysis. Fluorescence properties of the synthesized CQDs exhibited blue emission. The fluorescence quantum yield of the CQDs was around 11.37% at an excitation wavelength of 330 nm. The higher order nonlinear optical properties were examined using a Z‐scan technique and a continuous wave laser that was operated at a wavelength of 532 nm. Results demonstrated that the synthesis of CQDs can be considered as promising for optical switching devices, bio‐scanning, and bio‐imaging for optoelectronic applications.

Single crystals of pure and NaCl doped sulphamic acid (SA) were grown by slow evaporation method at room temperature. The lattice parameters and structure were determined by using single crystal and powder X-ray diffraction analyses. The presence of dopant in the SA lattice was affirmed by EDAX analysis. UV-Vis spectra show maximum transmittance in the visible region. The band gap energies were found to be 6.06 eV and 5.70 eV for pure and NaCl doped SA crystals respectively. From the PL specta the emission were observed at 335 and 424 nm for pure and 340 and 428 nm for doped SA crystal. The thermal stability of the grown crystals were analyzed by thermogravimetric and differential thermal analysis (TGA/DTA) and revealed that the grown crystals were thermally stable up to 331 °C and 334 °C for pure and NaCl doped SA. Vickers microhardness study reveals that the hardness of the crystals is increase with increasing load. The photoconductivity study shows that the grown crystals are negative photoconductive nature. The Laser Damage Threshold (LDT) indicates the grown crystals have good resistance to laser radiation than a standard Potassium dihydrogen phosphate (KDP) crystal. The Z-scan technique was employed to determine the nonlinear refractive index, nonlinear optical absorption and third order nonlinear optical (TONLO) susceptibility of the grown crystals using He–Ne laser.

“…Amino acid based semi‐organic crystals are known for NLO applications for several decades. [ 7 ] In particular, l ‐arginine monohydrochloride (LAHCl) has attracted much attention for frequency doubling, electro‐optic modulations, third‐order susceptibility effects such as nonlinear refraction, nonlinear absorption and optical limiting. [ 8–11 ] Therefore, LAHCl has been chosen as host material for the present work and organic azo dye (methyl orange) has been chosen as a dopant in order to analyze the changes in the optical limiting behaviors.…”

Chromophores in azo dyes are optically active and play an important role in modifying the optical nonlinear properties. Methyl orange (MO), an azo dye, has been chosen to dope with l‐arginine monohydrochloride (LAHCl), in order to tune the nonlinear optical properties. Pristine and MO doped LAHCl single crystals are grown by slow solvent evaporation method at ambient conditions. The grown crystals are confirmed by powder X‐ray diffraction and Fourier transform infrared studies. The crystals are subjected to linear and nonlinear optical characterizations. Decrease in optical band gap with increase in refractive index and birefringence are attributed to the increase in net macro‐polarizability of the doped LAHCl. Both pristine and MO doped crystals exhibit reverse saturable absorption (RSA) in Z‐scan measurements. The samples show optical limiting behavior under laser irradiation at 650 nm. The chromophore of MO has a significant role in enhancing RSA and optical limiting behavior of LAHCl.
