The determination of the age of building structures using the form of absolute dating that is now used by architects and archeologists is difficult and complex. A relatively large error of estimation can be observed in archeological studies. In the case of samples from the Middle Ages, such errors are not acceptable. The authors attempted to develop an alternative spectroscopic TL method for such studies, and proposed that the composition of bricks should be measured using X-ray diffraction, electron microscopy (EM) and TL spectra. The bricks for the testing were taken from internal walls and the walls in the attics of churches, i.e. from places built during the last stage of construction works. The TL measurements were made using x-ray and β source excitation within the temperature range of 25–500°C. Two different sizes of grains were studied: small (∼0.1 mm) and large (∼0.5 mm). A gothic church in Świebodzin from 1555, which has a well-known history of its construction, was selected for the investigations. Due to the fact that this church is 326 years younger than the two churches evaluated and described in [1], the composition of its bricks could be different. Therefore, the authors decided to compare the XRD data, EM results and TL spectra for bricks taken from all three churches. The intensities of the TL and the integrated TL intensities were determined. The measurement results are important for creating a relationship between the TL intensity and the date a building object was constructed. Moreover, thanks to this it was possible to verify the construction date of Saski Palace in Warsaw.</p></div>","PeriodicalId":52192,"journal":{"name":"Optical Materials: X","volume":"23 ","pages":"Article 100308"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590147824000202/pdfft?md5=9f31848effe6ede06519121ce5b3ca06&pid=1-s2.0-S2590147824000202-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141031197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molar ratio of appropriate acetates used during the synthesis, i.e., La(AcO)<sub>3</sub>:Gd(AcO)<sub>3</sub>:Tb(AcO)<sub>3</sub> was fixed to x:(0.95-x):0.05. Based on XRD measurements, the crystallization of hexagonal LaF<sub>3</sub> nanophase was verified without any admixture of GdF<sub>3</sub> phase, even for samples with La<sup>3+</sup>:Gd<sup>3+</sup> molar ratio ≤1. The optical characterization of fabricated Gd<sup>3+</sup>/Tb<sup>3+</sup> co-doped sol-gel materials involved the registration and analysis of photoluminescence excitation (PLE) and emission spectra (PL), as well as the decay curves for the <sup>6</sup>P<sub>7/2</sub> (Gd<sup>3+</sup>) and the <sup>5</sup>D<sub>4</sub> (Tb<sup>3+</sup>) excited levels. Upon excitation at λ<sub>ex</sub> = 275 nm wavelength, the fabricated sol-gel samples revealed the series of emission lines assigned to the electronic transitions from both dopants, i.e., Gd<sup>3+</sup> and Tb<sup>3+</sup>, indicating apparently the occurrence of Gd<sup>3+</sup>/Tb<sup>3+</sup> energy transfer process (ET). The photoluminescence measurements comprehensibly proved the competitiveness between Gd<sup>3+</sup> and Tb<sup>3+</sup> ions to be entered into LaF<sub>3</sub> fluoride nanocrystal lattice, formed during annealing of as-prepared xerogels. Based on the recorded PL spectra for fabricated sol-gel samples, some chromatic parameters were calculated, i.e., chromaticity coordinates (CIE), correlated color temperatures (CCT), and color purities (CP). The prepared Gd<sup>3+</sup>,Tb<sup>3+</sup> co-doped samples are able to emit green light with CCT values in a range from 5967 K to 6291 K, and high CP reached 70 %, which predispose them for use as efficient constituents for developing green-emitting devices.</p></div>","PeriodicalId":52192,"journal":{"name":"Optical Materials: X","volume":"23 ","pages":"Article 100336"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590147824000482/pdfft?md5=461cc283b4243991ab0a70eff7f3af30&pid=1-s2.0-S2590147824000482-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141596726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
