“…Bismite, which is the bismuth oxide stable phase, is a p-type semiconductor. It has been earlier used for smoke detection [28][29][30]. In combination with other typically used metal oxide semiconductors, it has been also used to sense CO, NO and H 2 [31][32][33][34].…”

“…They propose the Bi 2 O 3 as a highly selective oxide for NO detection. It had been earlier also used for the smoke detection [32]. The most widely used method for stabilization of α-Bi 2 O 3 (in term to get the defect structure of fluorite-type and high ionic conductivity at low temperature range) consists of doping with Mo, Y, V, Cu, Nb and Er atoms [33,34].…”

In this work the pulsed laser deposition (PLD) and the pulsed electron beam deposition (PED) techniques were used for fabrication of Mo-Bi 2 O 3 , La 1-x Sr x CoO 3 , La 1-x Ca x CoO 3 and Al-Mg thin films. An influence of ablation process basic parameters on the coatings structure and properties was discussed. Two types of laser ablation systems were applied: one equipped with a KrF excimer and second with a Q-switched Nd:YAG. Films were deposited on Si and MgO substrates. Scanning (SEM) and transmission (TEM) electron microscopy, atomic force microscopy (AFM) as well as X-ray diffraction (XRD) were used for structural analysis. Investigations focused on structure and chemical composition showed that smooth and dense thin films with nanocrystalline structure, preserving the composition of the bulk target, could be obtained by the both PLD and PED techniques. Research study showed that by a proper selection of PLD and PED process parameters it was possible to deposit films with significantly decreased amount and size of undesirably nanoparticulates.Keywords: PLD, PED, thin films, structure, doped oxidesOsadzanie laserem impulsowym (PLD) oraz osadzanie impulsową wiązka elektronową (PED) wykorzystane zostało do wytwarzania cienkich filmów typu: Mo-Bi 2 O 3 , La 1-x Sr x CoO 3 , La 1-x Ca x CoO 3 oraz Al-Mg. Dyskutowano wpływ podstawowych parametrów procesu ablacji na strukturę i właściwości uzyskiwanych powłok. Wykorzystane zostały dwa typy systemów do ablacji; jeden z ekscymerowym laserem KrF i drugi na bazie lasera Nd:YAG z modulatorem dobroci (Q-Switch). Filmy osadzano na podłożu Si i MgO. Skaningowa (SEM) i transmisyjna (TEM) mikroskopia elektronowa, mikroskopia sił atomowych (AFM), oraz dyfrakcja rentgenowska (XRD) wykorzystana została do analizy strukturalnej. Badania skoncentrowane na strukturze i skła-dzie chemicznym wykazały jednorodną i zwartą budowę cienkich nanokrystalicznych filmów uzyskanych metodami PLD i PED utrzymujących skład odparowywanych tarcz. Wykazano doświadczalnie, że odpowiednie dobranie parametrów procesu pozwala otrzymywać filmy o istotnym zminimalizowaniu ilości i wymiarów niekorzystnych nanocząstek w powłoce.
