“…In the case of transparent nanofillers, as silica nanowires (SiO 2 NWs), they could be embedded in polymeric matrices and processed by TP-DLW, allowing for the best performance in terms of resolution, when their refractive indexes are perfectly matched, eliminating the light scattering effects. This optimal condition could be achieved by tuning the refractive index of the polymer during the synthesis , or that of the SiO 2 NWs by adding a suitable dopant in the production process. − …”

This paper reports on the nanofabrication of a fiber-reinforced polymer nanocomposite (FRPN) by two-photon direct laser writing (TP-DLW) using silica nanowires (SiO 2 NWs) as nanofillers, since they feature a refractive index very close to that of the photoresist used as a polymeric matrix. This allows for the best resolution offered by the TP-DLW technique, even with high loads of SiO 2 NWs, up to 70 wt %. The FRPN presented an increase of approximately 4 times in Young’s modulus (8.23 GPa) and nanohardness (120 MPa) when compared to those of the bare photoresist, indicating how the proposed technique is well-suited for applications with higher structural requirements. Moreover, three different printing configurations can be implemented thanks to the use of silicon chips, on which the SiO 2 NWs are grown, as fabrication substrates. First, they can be effectively used as an adhesive layer when the laser beam is focused at the interface with the silicon substrate. Second, they can be used as a sacrificial layer, when the laser beam is focused in a plane inside the SiO 2 NW layer. Third, only the outer shell of the object is printed so that the SiO 2 NW tangle acts as the internal skeleton for the structure being fabricated in the so-called shell and scaffold printing strategy.

“…Еще одним способом стабилизации является внедрение КТ и их структур в полимерные матрицы. Для получения полимерных композитов предварительно синтезированные КТ помещают в раствор полимера и отверждают [52][53][54] или синтезируют их непосредственно в процессе полимеризации мономера [49,50]. Во втором случае светопропускание акриловых композиций полимер/полупроводник при длинах волн > 450 нм достигает 90−92% при толщине поглощающего слоя до 5 мм [48][49][50].…”

Photoluminescence of nanoscale structures based on zinc, cadmium and manganese sulfides depending on the conditions of synthesis and doping in the medium (poly)methylmethacrylate (PMMA). Photoluminescence excitation is associated with interband transitions of electrons in the semiconductor structures, absorption of optical radiation energy by defects in the crystal structure, as well as with the transfer of energy to the excited energy levels of Mn2+ ions. Luminescence occurs as a result of recombination processes at the levels of defects in the structure of the surface of particles and 4T1 → 6A1 transitions between the proper energy levels of Mn2+ ions. Based on changes in the photoluminescence spectra and photoluminescence excitation of PMMA/(Zn,Cd,Mn)S compositions, assumptions are made about the structure of particles. It is shown that their photoluminescence is affected by the distribution of Mn2+ ions in the structure of layers and on the surface of particles.
