Optical and structural studies on spray deposited α-PbO thin films

Abstract: Thin films of tetragonal lead monoxide have been prepared from spray pyrolytic decomposition of an aqueous solution of lead nitrate. The spray pyrolysis set-up developed for this study is also described briefly. From the structural investigations it has been found that the films generally grow with some admixture of monoclinic PbO 1.57 phase. The absorption coefficients of the films have been determined from transmittance measurements in the 400-1200 nm region. From an analysis of the room temperature optical … Show more

“…Due to its low electrical conductivity and interesting semiconducting and photo conducting properties, lead oxide seems to be an * E-mail: arbalu757@gmail.com attractive material for applications in laser technology and imaging devices [10]. Other applications are in the field of lead-containing high temperature superconducting films [11,12] and high refractive index materials [13]. Lead monoxide films have also been used as an anodic material for lithium secondary batteries [14].…”

“…Lead oxide thin films have been laid on by both physical and chemical deposition methods. Physical methods reported in the literature include pulsed laser-assisted deposition [17], dc and rf magnetron sputtering [18], while chemical methods include spray pyrolysis [13,14] and electro deposition [19]. Amongst the chemical methods used to fabricate lead oxide thin film, spray pyrolysis method is simple, inexpensive, and capable of producing films on large scale area for industrial applications.…”

“…For α-PbO system in which the orbital overlap between layers controls the size of the band gap, it results in a compensation effect [5]. In particular, for the lattice parameters optimized with GGA (a 0 =4.06Å and c 0 =5.51Å [5]), the band gap is only slightly underestimated, as 1.8 eV to be compared with the experimental value of 1.9 eV [13] (for this compound, good agreement of the size of the band gap estimated theoretically with that found experimentally has been pointed out in earlier work as well [11]). Application of the experimental value of the lattice parameters causes the band gap to shrink by 0.22 eV [5].…”

“…Таким же методом в [66] показано, что происхождение носителей в нелегированном материале обусловлено кислородными вакансиями, которые формируют донор-ные состояния в резонансной зоне проводимости. Шири-на непрямой запрещенной зоны здесь оценена в 1.8 eV, в хорошем согласии с экспериментом 1.9 ± 0.1 eV [67]. Согласно [62], β-PbO имеет непрямую запрещенную зону шириной 2.57 eV.…”
