Graphene quantum dots have large surface area, high photostability, excellent biocompatibility and versatile photoluminescence, promising for various applications.
Functionalizing glass with optically active quantum dots has shown great potential in near-infrared bioimaging and optical communication. However, the size distribution of is hard to control by traditional quenching method due extremely high processing temperature (∼1300 °C), resulting unexpected transmission loss luminescent embedded a composite. Herein, we developed nanoconfined synthesis lead sulfide (PbS) mesoporous aluminosilicate matrix at relatively low 600 °C adjustable broadband...
Photo-darkening and photo-bleaching are well known phenomena in As-Se Ge-Se chalcogenide glasses, respectively. Consequently, a systematic dependence of photo-induced optical changes Ge(x)As(45-x)Se(55) glass series on x is expected between these two extremes. This prediction photosensitivity Ge/As ratio has been exploited to demonstrate the first intrinsically photo-stable at approximately 10, which would be suitable for fabricating photo-insensitive components various applications.
Large-scale vertically aligned ZnO nanowires with high crystal qualities were fabricated on thin graphene oxide films via a low temperature hydrothermal method. Room photoluminescence results show that the ultraviolet emission of grown was greatly enhanced and defect-related visible suppressed, which can be attributed to improved quality possible electron transfer between oxide. Electrochemical property measurement demonstrated nanowires/graphene have large integral area cyclic voltammetry...
Graphene sheets with an adjustable number of layers and a low defect density were prepared by exfoliation microwave-assisted expanded graphite in the aqueous phase assistance cetyltrimethylammonium bromide. The graphene exhibit excellent film-formation ability, showing potential applications optical electrical device fields.
We demonstrate crystals (LiNbO(3)-like) that were space-selectively nucleated and grown in the bulk of silica-based glass by femtosecond laser irradiation at a high repetition rate (typ. 300 kHz). Oriented with their polar axis mostly aligned or perpendicular to scanning direction have been fabricated manipulation temperature gradient adjusting parameters. The mechanism for orientation laser-induced crystallization is briefly discussed.
Sodium phosphosilicate glasses exhibit unique properties with mixed network formers, and have various potential applications. However, proper understanding on the structures property-oriented methodology based compositional changes are lacking. In this study, we developed an extended topological constraint theory applied it successfully to analyze composition dependence of glass transition temperature (Tg) hardness sodium glasses. It was found that Tg do not always increase content SiO2,...
We report selective metallization on surfaces of insulators (glass slides and lithium niobate crystal) based femtosecond laser modification combined with electroless plating. The process is mainly composed four steps: (1) formation silver nitrate thin films the glass or crystal substrates; (2) generation particles in irradiated area by direct writing; (3) removal unirradiated films; (4) plating modified area. discuss mechanism insulators. Moreover, we investigate electrical adhesive...
