A novel and effective method to improve scintillation properties of glass-ceramics, such as intensity enhancement and decay-time shortening, is reported in this work. Compared with crystal scintillators, glass scintillators always have the problems of low efficiency and long decay; how to solve them has always been a scientific puzzle in the field of scintillation glass-ceramics. The plasma enhancement effect can be predicted to solve the above problems. Ag+ ions were diffused into glasses by ion exchange, and then Ag nanoparticles and CsPbBr3 quantum dots were formed by heat treatment. The structure of the CsPbBr3 perovskite consists of a series of shared corner PbBr6 octahedra with Cs ions occupying the cuboctahedral cavities. By using Ag and the plasma resonance effect, the photoluminescence intensity of CsPbBr3 quantum dot glasses was enhanced by 3 times, its radioluminescence intensity increased by 6.25 times, and its decay time was reduced by a factor of more than one. Moreover, the mechanism of photoluminescence and radioluminescence enhanced by Ag and plasma was discussed based on the experimental results and finite-difference time-domain method. We concluded that the increase in radioluminescence intensity was related to plasma enhancements and the energy exchange between Ag nanoclusters and CsPbBr3 quantum dots. Doping Ag is a valid means to improve the scintillation luminescence of CsPbBr3 quantum dot glasses, which can be applied in the field of scintillation.

“…Research on the optical modification of the common 2D materials is quite advanced, however, some of the methods described in this review, for instance, lack of doping and ablation demonstration even for well‐known materials, such as hBN and phosphorene. Moreover, there is still a large group of novel 2D materials and many other low‐dimensional materials, for example, perovskites, [ 185 ] 2D polymers, and different van der Waals heterostructures, with only few reported optical modification results. To illustrate, heterostructures could be created with defined twisting angles (e.g., for twistronics) and 3D structures via optical‐modification‐based strain and topographical engineering.…”

on the same chip, which is promising for integrated electronics or photonics applications, [7] such as lasers, [8][9][10] optical modulators, [11] and photodetectors. [12] Indeed, 2D materials are an excellent candidate for postsilicone electronics due to their unique properties, versatile scaling of channel length, reduced device dimensionalities, and the possibility of creating circuits nearly at the atomic level. [13] Currently, some of the biggest challenges for 2D material synthesis include the lack of large-scale manufacturing and the necessity of harsh or arduous microand nanofabrication methods. Typical fabrication methods are based on chemical vapor deposition (CVD) and mechanical exfoliation from bulk crystals. The former involves a process that results in layers with relatively high concentrations of atomic impurities, [14] and the latter is limited in producing large area flakes. [14] Further fabrication steps for the incorporation of 2D materials into integrated devices typically require processes like electron-beam lithography and reactive ion etching, [15] both of which can be harmful to flakes that are atomically thin.All-optical processing of 2D materials has been demonstrated to overcome limitations of the conventional synthesis methods. It is time-and cost-effective, and it is also a promising fabrication alternative over CVD and mechanical exfoliation. Optical modification processes offer selectivity, locality, directionality, tunability, less harmful conditions, and on-demand functionalities, such as optical doping, [16][17][18][19] oxidation, [20][21][22][23] optical thinning, [24][25][26][27][28] and phase change. [29][30][31][32] Additionally, almost all of the optical modification and fabrication methods can be used for laser-direct writing (LDW) of patterns and structures at the microscale. [33][34][35][36] The high precision of LDW is particularly advantageous in the evolving world of nanofabrication. Lasers allow local modification of 2D material electronic bandgap, [37] thickness, [25] strain, [33,[38][39][40] and chemical composition, [19,41,42] even beyond the diffraction limit. [33] The created structures and patterns can often be directly used for applications in sensors, [22] energyprocessing devices, [43] and holography [44] (Figure 1). All the major demonstrations using LDW on 2D materials are listed in Table 1. Here, we review the optically assisted synthesis and fabrication methods of 2D materials, and their state-of-theart applications, providing detailed descriptions and features of optically engineered devices using 2D materials. We have straightforwardly introduced light-matter interactions and 2D-material-light interactions, and we also present our perspectives on this emerging field.2D materials are under extensive research due to their remarkable properties suitable for various optoelectronic, photonic, and biological applications, yet their conventional fabrication methods are typically harsh and costineffective. Optical modification is demonstrated as an effective an...

Plasmon‐based devices have founded numerous applications in photonics based on optically excited strong near‐field effect at nanoscale. So far, the large‐area fabrication of periodic plasmonic nanostructures is still challenging due to a small write‐field limitation of lithography‐based techniques, especially for metallic substrates. A novel strategy is proposed to fabricate millimeter‐sized patterns of periodic plasmonic nanostructures inside dielectric materials (glass) through a femtosecond laser direct‐write plasmonic nanolithography approach. Noble metal nanoparticles are formed by the ion implantation in glass and reshaped into a nanowire‐like nanoparticles’ assembly by direct writing with femtosecond laser harnessing plasmonic interaction. As‐designed patterns at nanoscale are inscribed by this type of plasmonic lithography to form wires composed of nanoparticles. Examples for applications, the linear dichroism response, and structural color have been achieved by the plasmonic nanogratings buried inside glass (i.e., at subsurface regions). The work opens a new avenue to manipulate metallic nanoparticles in solids by direct plasmonic nanolithography and offers a reliable implementation of large‐area fabrication of plasmonic nanostructures for diverse range of photonic applications.
