We herein report a rapid and effective method for the synthesis of graphene oxide quantum dots (GOQDs) with excellent linear and nonlinear optical properties. The GOQDs were prepared by chemical cutting of graphite oxide and characterized using Fourier transform infrared spectroscopy, X-ray diffraction, UV-Vis absorption spectroscopy, Raman spectroscopy and transmission electron microscopy. The Commission International de l'É clairage 1931 chromaticity coordinates for GOQDs (x = 0.21, y = 0.23) demonstrated that highly pure blue-light emission was achieved upon 330 nm excitation wavelength. Optical nonlinearity measurements conducted at 532 nm using 5 ns laser pulses indicated saturable absorption behavior, which tends to the onset of reverse saturable absorption as the input light fluence was increased.

“…Zhan and co-workers reported the efficient synthesis of graphene embedded in sol-gel Ormosil glasses. [376,377] They used both nanosheets (GONSs) and nanoribbons (GONRs) (Figure 32). The prepared materials showed high linear transmission in the visible, good thermostability and good optical limiting response attributed to both nonlinear scattering and nonlinear absorption.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…[47][48][49][50][51] Suppression of the output fluence has been shown mostly in graphene-based solutions which allow the possibility of a strong nonlinear component due to scattering. However since such materials in suspension form are not practical components for to integrate into a structure the challenge has been to develop graphene films in solid matrices [52] which are better suited for a device platform.…”
