Amorphous lead titanate: A new wide-band gap semiconductor with photoluminescence at room temperature
(2000-01-01)
This paper describes a new amorphous wide-band gap semiconductor with photoluminescence (PL) at room temperature. The amorphous PbTiO3 was prepared by a sol-gel-like process in powder and thin film form. The optical property ...
Optical and structural properties of W03 as a function of the annealing temperature
(2012-11-27)
This work presents a study of effect of annealing temperatme on optical and structural properties of W03 that has been deposited by hot-filament metal oxide deposition (HFMOD). X-ray diffraction shows that the ...
Physical properties characterization ofW03 films grown by hot-filatnent metal oxide deposition
(2012-11-27)
W03 is grown by hot-filament metal oxide deposition (HFMOD) technique under atmospheric pressure and an oxygen atmosphere. By X-ray diffraction obtains thatW03 presents mainly monoclinic crystalline phase. The chemical ...
