“…Moreover, M. Shoji et al [8] first reported that a single phase Y 2 O 2 SO 4 :Eu 3þ phosphor was synthesized by high energy ball milling followed by heat treatment using Y 2 O 3 and carbon disulfide (CS 2 ) as starting materials. Lixin Song et al [14] synthesized the Y 2 O 2 SO 4 :Eu 3þ nanopieces via a combined method of electrospinning and heat treatment in mixed gas of sulfur dioxide (SO 2 ) and air. But the methods mentioned above usually have the drawbacks of high processing temperature, release of environmentally hazardous SO 2 gas, utilizing toxic CS 2 liquid, and uncontrollable morphology of the product.…”

“…Herein, the optimum doping concentration is 10% in Y 2 O 2 SO 4 :Tb, whereas LYH:Tb NCs is 30%, which is due to the transition of hydroxides to oxides and the loss of hydroxyl and water molecules. Therefore, the clustering of Tb ions in Y 2 O 2 SO 4 unit cell leads to the intensification of nonradiative energy transfer or energy loss, resulting in concentration quenching . Importantly, as‐prepared Y 2 O 2 SO 4 : x %Tb ( x = 1, 10, 20, 30, 40) retain the original morphological features, a typical SEM image of Y 2 O 2 SO 4 :10%Tb, as given in Figure d, verifies the conical objects with a hollow interior.…”

positively charged octahedral hydroxide host layers and hydrated anions intercalated in the interlayer gallery. [9][10][11][12] The well-known LDHs, with a general formula of M 2+1-x M 3+ x (OH) 2 A n− x/n ·mH 2 O (M 2+ and M 3+ , the bivalent and trivalent metal cations, respectively; A n− , the nonframework charge-balancing anions), are a class of hydrotalcite-like hydroxides, e.g., Mg 6 Al 2 (OH) 16 (CO 3 )·4H 2 O, namely anionic clay found in nature, important in geochemistry, mineralogy, and materials science. [13,14] In recent years, the M 2+ −Al 3+ LDHs have been widely pursued due to the facts that it is very difficult to fabricate non-Al 3+ LDHs via a homogeneous precipitation. [15][16][17] Very recently, we have developed an innovative method to prepare all-transition-metal LDHs through the topological transformation of the corresponding transition-metal brucite hydroxides (M 2+ (OH) 2 ) by halogen oxidation in organic solvent. [18] LMHs, with the common formula of M 2+ (OH) 2-x A n− x/n ·mH 2 O, have an analogous structure as LDHs and consist of positively charged brucite-like host layers with charge-balancing anions in the gallery, which have recently attracted tremendous attention as electrode materials in supercapacitors and catalysts in water splitting. [19][20][21][22] Partly due to their tunable parameters such as the diversity of cations (M 2+ and/or M 3+ ) in hydroxide host layers, inorganic/organic anion (A n− ) in the interlayer gallery, layered hydroxides involve a large family of isostructural materials with outstanding intercalation and anion-exchange capability.In particular, layered rare-earth hydroxides (LRHs), with a general chemical formula of RE(OH) 2.5 (A n− ) 0.5/n ·nH 2 O (RE: trivalent rare-earth cations; A n− : interlayer n-valent anions), as a new and important class of functional layered hydroxides, have attracted extensive interest duo to their unique luminescence and electronic properties as well as significant applications in various fields, such as high performance luminescence, upconversion materials, downconversion materials, and so forth. [23][24][25] LRHs have been successfully synthesized in recent years through homogeneous precipitation method by using soluble rare-earth salts as the RE source and hexamethylenetetramine (C 6 H 12 N 4 , HMT) as a hydrolysis agent. [26] However, most of It is demonstrated herein that a series of terbium ions (Tb3+ )-doped layered yttrium hydroxide (LYH:Tb) nanocones (NCs) intercalating dodecyl sulfate (C 12 H 25 SO 4 , DS) anions can be successfully synthesized in large quantities through a facile hydrothermal strategy. The DS anions in the interlayer gallery of LYH:Tb NCs can be readily modified with various anions (such as NO 3 − , Cl − , and CH 3 COO − ) through a convenient anion-exchange procedure. The luminescent properties of LYH:Tb NCs are sensitively influenced by the dopant concentration and the interlayer anions. In particular, the original DS − -intercalated form and the anion-exchanged product can be topotactically convert...

The traditional way for determination of molecular groups structure in crystals is the X-Ray diffraction analysis and it is based on an estimation of the interatomic distances. Here, we report the analysis of structural units in Y2O2SO4 using density functional theory calculations of electronic properties, lattice dynamics and experimental vibrational spectroscopy. The Y2O2SO4 powder was successfully synthesized by decomposition of Y2(SO4)3 at high temperature. According to the electronic band structure calculations, yttrium oxysulfate is a dielectric material. The difference between the oxygen–sulfur and oxygen–yttrium bond nature in Y2O2OS4 was shown based on partial density of states calculations. Vibrational modes of sulfur ions and [Y2O22+] chains were obtained theoretically and corresponding spectral lines observed in experimental Infrared and Raman spectra.
