نویسندگان
چکیده
The composite material based on ZnO microneedles and Alq3 thin film has been obtained. photoluminescence study shows a tenfold enhancement in the band-edge UV emission (390 nm) of 2 × visible hybrid composite, when excited by 266 nm laser beam. This can be explained interaction between molecules energy transfer from to molecule. Discussed structures find interesting applications as emitting layers OLED devices.

Correlation between crystal structure and optical properties of copper- doped ZnO thin films
ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...

متن کاملImprovement of optical transmittance and electrical properties for the Si quantum dot-embedded ZnO thin film
A Si quantum dot (QD)-embedded ZnO thin film is successfully fabricated on a p-type Si substrate using a ZnO/Si multilayer structure. Its optical transmittance is largely improved when increasing the annealing temperature, owing to the phase transformation from amorphous to nanocrystalline Si QDs embedded in the ZnO matrix. The sample annealed at 700°C exhibits not only high optical transmittan...
