Compound 1 is characterized by a two-dimensional (2-D) layer-like structure, while compound 2 features a one-dimensional (1-D) chain-like structure. The lanthanide ions in both compounds are eight coordinated and show a square antiprism geometry. The mercury ions exhibit various coordination motifs. Compound 1 exhibits ultraviolet upconversion photoluminescence emission, whereas compound 2 displays red photoluminescence. The photoluminescence emissions arise from the characteristic 4f electron intrashell transitions of the 6P7\/2 \u2192 8S7\/2 of the Gd3+ ions in compound 1 and the 4F9\/2 \u2192 4I9\/2, 4F7\/2 + 4S3\/2\u2192 4I9\/2, 4F5\/2 + 2H9\/2\u2192 4I9\/2, 4F3\/2 \u2192 4I9\/2 of the Nd3+ ions in compound 2. Compound 2 has CIE (Commission Internationale de l\u2019\u00c9clairage) chromaticity coordinates of (0.7142, 0.2857) and its CCT (correlated color temperature) is 138,224 K. Solid-state UV\/Vis diffuse reflectance spectra revealed that the semiconductor band gaps of the compounds are 3.12 eV and 3.23 eV, respectively. Elemental analyses and FT-IR spectroscopy were carried out to confirm the purity of the compounds.<\/jats:p>","DOI":"10.17344\/acsi.2024.8937","type":"journal-article","created":{"date-parts":[[2024,12,13]],"date-time":"2024-12-13T15:03:02Z","timestamp":1734102182000},"page":"685-695","source":"Crossref","is-referenced-by-count":3,"title":["Syntheses, Crystal Structures and Characterization of Two New Lanthanide Mercury Halide Compounds"],"prefix":"10.17344","volume":"71","author":[{"given":"Xi-Yu","family":"Shao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao-Dong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Long-Hua","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Yue","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Tong","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheng-Ping","family":"Dai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang-Wang","family":"Pan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7072","published-online":{"date-parts":[[2024,12,20]]},"container-title":["Acta Chimica Slovenica"],"original-title":[],"deposited":{"date-parts":[[2024,12,13]],"date-time":"2024-12-13T15:03:13Z","timestamp":1734102193000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.matheo.si\/index.php\/ACSi\/article\/view\/8937"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,20]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2024,12,20]]}},"URL":"https:\/\/doi.org\/10.17344\/acsi.2024.8937","relation":{},"ISSN":["1580-3155"],"issn-type":[{"value":"1580-3155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12,20]]}}}
