Ion implantation induced phase transformation and enhanced crystallinity of as deposited copper oxide thin films by pulsed laser deposition

Hollow Pentagonal-Cone-Structured SnO2 Architectures Assembled with Nanorod Arrays for Low-Temperature Ethanol Sensing

“…Moreover, two Raman scattering peaks at 578 and 693 cm –1 are also observed. These two minor shoulder features might originate from surface imperfections of the oxygen vacancy on the surface, and the increase in the intensity is mainly attributed to the increase in oxygen vacancy concentration caused by the decrease in particle size, , which is supported by the results of HRTEM. The higher oxygen vacancy concentration on the surface could enhanced the gas response …”

Copper Oxides on a Cu Sheet Substrate Made by Laser Technique

“…Methods like thermal oxidation [ 2 , 5 , 6 , 7 , 8 , 9 ], magnetron sputtering [ 4 ] and atomic layer deposition (ALD) [ 10 ] are commonly used to manufacture copper oxides. So far, laser treatment has been used for copper sheet cleaning [ 11 ], welding [ 12 , 13 ] and cutting [ 14 ], along with copper oxide deposition by pulsed laser deposition (PLD) [ 15 ] or copper oxide sintering [ 16 ]. With the highest frequency, near infrared (NIR) laser has been adopted for copper welding [ 13 ], cutting [ 14 ] and other processes [ 16 , 17 , 18 , 19 ].…”

Haubold et al proposed using a green laser for Cu welding [ 14 ], and Onyszczuk et al proposed using this laser type for copper sheet cleaning [ 11 ].…”

“…For PLD copper oxide deposition, UV lasers are applied [ 15 , 20 ]. Only one paper from 1983 mentions copper sheet oxidation using an IR laser [ 16 ]. The attractiveness of laser technology arises from the possibility of precise microtreatment of surfaces due to the use of a laser beam as a noncontact, automated tool [ 21 , 22 , 23 ].…”

Hydrothermal synthesis of flower cluster-shaped ZnO microstructures with sodium lignosulfonate as structure-directing agent

“…As a result, various methods have been used to fabricate nanostructured ZnO, such as hydrothermal synthesis [6], chemical vapor deposition [7], sol-gel method [8], solvothermal synthesis [9], and pulsed laser deposition [10]. Among the above-mentioned methods, the hydrothermal synthesis is an effective and promising method with low cost, low reaction temperature, high yield, easy operation, simple equipment, no need of vacuum or carrier gas and environmental friendliness, etc.…”
