Journal ArticleDOI
Preparation of carbon quantum dots with tunable photoluminescence by rapid laser passivation in ordinary organic solvents
Xiangyou Li,Hongqiang Wang,Yoshiki Shimizu,Alexander Pyatenko,Kenji Kawaguchi,Naoto Koshizaki +5 more
TL;DR: As-prepared carbon dots exhibited visible, tunable and stable photoluminescence (PL), and XPS analysis showed that the increased oxygen concentration might be concerned with the origin of PL.
Journal ArticleDOI
Single-Crystalline Rutile TiO2 Hollow Spheres: Room-Temperature Synthesis, Tailored Visible-Light-Extinction, and Effective Scattering Layer for Quantum Dot-Sensitized Solar Cells
Hongqiang Wang,Hongqiang Wang,Masahiro Miyauchi,Yoshie Ishikawa,Alexander Pyatenko,Naoto Koshizaki,Yue Li,Yue Li,Liang Li,Liang Li,Xiangyou Li,Yoshio Bando,Dmitri Golberg +12 more
TL;DR: In this paper, a general synthesis of inorganic single-crystalline hollow spheres has been achieved through a mechanism analogous to the Kirkendall effect, based on a simple one-step laser process performed at room temperature.
Journal ArticleDOI
Synthesis of Spherical Silver Nanoparticles with Controllable Sizes in Aqueous Solutions
TL;DR: In this article, a new method that combines the seed technique with laser treatment of a synthesized colloid was used to prepare spherical, almost monodisperse silver nanoparticles ranging in diameter from 10 to 80 nm (± 10%).
Journal ArticleDOI
Selective Pulsed Heating for the Synthesis of Semiconductor and Metal Submicrometer Spheres
Hongqiang Wang,Alexander Pyatenko,Kenji Kawaguchi,Xiangyou Li,Zaneta Swiatkowska-Warkocka,Naoto Koshizaki +5 more
TL;DR: Spherical particles are of great interest because of their potential to obtain interesting and useful functionalities in many fields of application, such as photonic crystals, biomedicine, sensing,alysis, environmental remedies, and solar cells.
Journal ArticleDOI
Mechanism of pulse laser interaction with colloidal nanoparticles
TL;DR: In this paper, the particle heating- melting-evaporation model is applied to the interaction mechanism of the laser beam with nanoparticles to control the laser processing of different nano-objects.
