The influence of the addition of ZnO nanoparticles (~20 nm in size) or CuO nanoparticles (~5 nm in size) in the ZnPc:TPyP mixture and the impact of the added metal oxide amount on the properties of the obtained composite films were evaluated in comparison to a reference layer based only on an organic blend. Thus, in the case of nanocomposite films, the vibrational fingerprints of both organic compounds were identified in the infrared spectra, their specific strong absorption bands were observed in the UV\u2013Vis spectra, and a quenching of the TPyP emission band was visible in the photoluminescence spectra. The morphological analysis evidenced agglomerated particles on the composite film surface, but their presence has no significant impact on the roughness of the MAPLE deposited layers. The current density\u2013voltage (J-V) characteristics of the structures based on the nanocomposite films deposited by MAPLE revealed the critical role played by the layer composition and component ratio, an improvement in the electrical parameters values being achieved only for the films with a certain type and optimum amount of metal oxide nanoparticles.<\/jats:p>","DOI":"10.3390\/ma16062480","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T02:36:22Z","timestamp":1679366182000},"page":"2480","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Macrocyclic Compounds: Metal Oxide Particles Nanocomposite Thin Films Deposited by MAPLE"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2010-7318","authenticated-orcid":false,"given":"Marcela","family":"Socol","sequence":"first","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicoleta","family":"Preda","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4030-360X","authenticated-orcid":false,"given":"Carmen","family":"Breazu","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7267-3947","authenticated-orcid":false,"given":"Andreea","family":"Costas","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7901-0361","authenticated-orcid":false,"given":"Oana","family":"Rasoga","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela","family":"Petre","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"},{"name":"Faculty of Physics, University of Bucharest, 405 Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0941-080X","authenticated-orcid":false,"given":"Gianina","family":"Popescu-Pelin","sequence":"additional","affiliation":[{"name":"National Institute for Lasers, Plasma and Radiation Physics, 409 Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6745-9711","authenticated-orcid":false,"given":"Sorina","family":"Iftimie","sequence":"additional","affiliation":[{"name":"Faculty of Physics, University of Bucharest, 405 Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9720-8857","authenticated-orcid":false,"given":"Andrei","family":"Stochioiu","sequence":"additional","affiliation":[{"name":"Faculty of Physics, University of Bucharest, 405 Atomistilor Street, 077125 Magurele, Romania"},{"name":"National Institute for Lasers, Plasma and Radiation Physics, 409 Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1992-7346","authenticated-orcid":false,"given":"Gabriel","family":"Socol","sequence":"additional","affiliation":[{"name":"National Institute for Lasers, Plasma and Radiation Physics, 409 Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7755-1685","authenticated-orcid":false,"given":"Anca","family":"Stanculescu","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor Street, 077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2002041","DOI":"10.1002\/adom.202002041","article-title":"Multifunctional Stretchable Organic\u2013Inorganic Hybrid Electronics with Transparent Conductive Silver Nanowire\/Biopolymer Hybrid Films","volume":"9","author":"Park","year":"2021","journal-title":"Adv.
