Optical limiting property of gold nanorods/ormosil gel glass composites

AurOrGlass: ORMOSIL Sol‐Gel Glasses Functionalized with Gold Nanoparticles for Advanced Optical Applications

“…Similarly, by exploiting the wide nanochemistry of Au nanocrystals (for example with the alkanethiolate chain length) the electronic and thus the optical properties of gold nanoparticles can be modulated in an ample range, whereas the sol‐gel entrapment in the ORMOSIL sol‐gel cages provides the high photostability during prolonged illumination required for practical application …”

“…Noting the importance of protection materials against the laser damage, the team concluded that this nanocomposite material is a promising candidate for optical limiter, especially due to the enhanced thermal stability of the ORMOSIL glass matrix …”

“…This is clearly shown by the behaviour of Au nanorods entrapped in an ORMOSIL obtained from 3‐mercaptopropyl trimethoxysilane (MPS) and TEOS …”

“…Which advances in nanochemistry can be applied to further expand control on the SPR and other optical properties of these glasses? Which hurdles need to be overcome to realize the potential of at least some of the “plethora of applications” mentioned in the introductory text of almost all optical research articles devoted to silica‐based materials functionalized with Au nanocrystals?…”
