Improved photocurrent properties of La doped CuO thin films coated by nebulizer spray pyrolysis method for photosensor applications

Breaking Boundaries in LED Technology: Exploring the Revolutionary Diode Characteristics of Screen Printed (TiO2)1−x (CuO)x Thick Films

“…The mean crystallite size (D) is calculated by using the Debye-Scherrer formula. 25 The calculated crystallite size of the maximum diffraction peak (101) is 33.31 nm and 35.81 nm for anatase TiO 2 and CuO-doped TiO 2 respectively. The average crystallite sizes of the TiO 2 -CuO composite were higher and it showed a little crystal structure distortion.…”

Improvement in photo-device properties of CuO thin films for opto-electronic applications: effects of (Ni, Co) co-doping

“…The PL emission peaks observed at 415 nm, and 451 nm in the violet to blue regions could be correspond to Cu-defects [32,36]. The strong emission peak identified at 477 nm is due to oxygen vacancies [37]. The PL green emission peak observed at 521 nm in the visible region was attributed to the electron-hole recombination, where electrons occupy singly ionized oxygen vacancies in pure CuO as well as Ni and/or Co-doped CuO thin films [36,38].…”

“…The PL green emission peak observed at 521 nm in the visible region was attributed to the electron-hole recombination, where electrons occupy singly ionized oxygen vacancies in pure CuO as well as Ni and/or Co-doped CuO thin films [36,38]. It may also be attributed to various structural defects present in the films [37]. It is found that the shape and position of all the defect centers are due to the added dopants were remain unchanged and only the intensity of all the emission peak is increased and attained maximum for CuO:Ni(1%):Co(1%) thin film.…”

Green hydrothermally synthesized ultrathin Mg-doped CuO nanoflakes: a structural, electrical and dielectric study

“…40 Fe-doped CuO has a slightly higher band gap and electrical conductivity than undoped CuO due to the formation of oxygen vacancies. 41 Moreover, enhanced photosensitive CuO nanostructures have been produced by doping with Cd, 42 Co, 43 Ag, 44 Ba 45 or La, 46 which is crucial for many applications including hydrogen production, photodetection and photocatalysis. Heavily Ru-doped CuO shows superconducting features, 47 while forming complex compounds of nanostructured CuO with magnetic ions can introduce ferromagnetic ordering.…”
