The sample compositions were analyzed using atomic absorption spectroscopy. It was found that changes in stoichiometry had a negligible effect on the crystalline phase and optical properties of the films, whereas variations in dopant concentration significantly altered their surface morphology and luminescence properties. The absorption edge of ZnS, determined using absorption spectroscopy was found to be blue-shifted from its bulk counterpart due to the confinement effect. The photoluminescence (PL) properties of the undoped and Mn:Cu co-doped ZnS samples have been studied in detail. The PL spectra of undoped samples consisted of a broad asymmetric peak which, upon deconvolution, was correlated with band edge transition and radiative recombination via intrinsic defect states. In contrast, doped samples showed intense Gaussian peaks positioned differently from the undoped samples, indicating the substitution of dopants at the zinc site in the ZnS lattice. The peak intensity also varied with changes in doping percentages in the samples. In this study, a high luminescence yield was achieved even at very low dopant concentrations.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of a P2&lt;sub&gt;1&lt;/sub&gt;/n monoclinic structure in every composition was determined by analyzing the diffraction patterns at room temperature. The consistency in the peak positions in all the compositions indicates that Mn&lt;sup&gt;3+&lt;/sup&gt; is successfully substituted for La&lt;sup&gt;3+&lt;/sup&gt;. Rietveld refinement revealed changes in the unit cell’s volume upon Mn doping. The &lt;i&gt;x&lt;/i&gt; = 0 (parent compound) exhibited a double perovskite structure of the ordered type. Variations in the bond angles and lengths are observed across all compositions. Octahedral tilting is observed in all compositions brought about by variations in the tolerance factor ‘t’ and the tilting angle ‘ɸ.’ The FTIR spectra confirm the perovskite structure with characteristic vibrational features indicative of perovskite-type bonding and Mn substitution effects. The 472–488 cm&lt;sup&gt;−1&lt;/sup&gt; peaks can be attributed to Mn–O and Li–O stretching vibrations, observed peak shifts with increasing &lt;i&gt;x&lt;/i&gt; indicating local structure modification, and possible Mn-induced strain in the lattice. Strong absorption bands observed at 662–686 cm&lt;sup&gt;−1&lt;/sup&gt; correspond to Te–O stretching vibrations within the TeO&lt;sub&gt;6&lt;/sub&gt; octahedra, confirming the presence of Te in the perovskite structure. UV–visible studies revealed decreased band gap energy from 4.3 eV in the undoped composition to 2.17 eV in the doped composition (&lt;i&gt;x&lt;/i&gt; = 0.3) with increasing Mn content, suggesting enhanced conductivity. This also indicates that Mn doping introduces new electronic states within the band gap, thereby reducing the energy for the required electronic transitions. The observed transitions in the UV region, involve d-d transitions within the Mn&lt;sup&gt;3+&lt;/sup&gt; ions combined with the charge transfer from the oxygen ligands to Mn&lt;sup&gt;3+&lt;/sup&gt;&lt;i&gt;.&lt;/i&gt; Raman spectra recorded for all compositions indicated the symmetry is the same for all compositions and the successful doping of Mn into the parent compound.
