Synthesis and Optical Properties of Ce-doped ZnO

A study of structural, optical and magnetic properties of Zn0.97−xCuxCr0.03O diluted magnetic semiconductors

“…To make the comparison clear, the PL spectrum of pure ZnO is also illustrated here. We can observe that all the spectra contain a strong UV band peak around 380 nm, which commonly originates from excitonic recombination corresponding to the near-band-edge emission of ZnO [34,35] . Compared with pure ZnO, on the one hand, for the PL spectra from Zn 0.97−x Cu x Cr 0.03 O (x = 0, 0.01, 0.02), the peak position of UV emission exhibits a blue shift with Cu doping concentration increasing to 0.02.…”

Characterization of ZnO films prepared by sol-gel method

“…In addition, ZnO also has a rich source of raw materials, low price, non-toxic, easy to achieve doping and so on. Therefore, ZnO is a very promising material for ultraviolet optoelectronic devices, and it has wide application prospects in UV emitting devices, ultraviolet laser devices and other fields [5,6].…”

A New Method on the Position Analysis of 3-Dof 3-P_C(RR)_N Spherical Parallel Mechanism

“…) spherical parallel mechanism is widely used in large equipments, for instance, robot's waist, shoulder and wrist, NC rotary platform, large radio telescope, satellite tracking antenna orientation and vibration test-bed and so forth, for its high stiffness, strong bearing, minor error, high precision, simple structure, easy control, etc [1,2].…”
