Thermally stimulated luminescence of undoped and Ce3+-doped Gd2SiO5 and (Lu,Gd)2SiO5 single crystals

Influence of Lu content on (LuxGd1-x)2SiO5 oxyorthosilicates grown by Laser Floating Zone: Structural studies and transparency

“…LGSO-5 have a monoclinic C2/c structure. These results follow the structural phase transition observed for (LuxGd1-x)2SiO5 (LGSO) oxyorthosilicate materials that exhibit a GSO-type (P21/c) structure for x<0.15 and LSO-type (C2/c) when x>0.17 [5][6][7][8][9][10][11][12][13][14].…”

“…On the other hand, EDS analysis performed confirms the homogeneity of fibres, revealing a uniform composition without presence of secondary or eutectic phases, as could be expected from the LFZ treatment of Lu2O3/SiO2 mixtures [17]. It must be noted that compositions calculated from EDS analysis are close to initial mixtures (Table II), in opposition to compositional dissimilarity observed for LGSO materials developed by conventional CZ method [5][6][7][8][9][10][11][12]. Anyway, aiming to reduce fabrication costs associated to LSO materials by standard methods like CZ, LFZ results more suitable from the environmental point of view (growth in ambient conditions) and time reduction.…”

“…Since Loutts et al [12] produced LGSO for first time in 1997, to our knowledge, most studies related to its synthesis involve the use of the Czochralski (CZ) method [5][6][7][8][9][10][11][12]. Only Zorenko et al [13,14] reported other technique such as liquid phase epitaxy for the growth of single crystalline films.…”

“…Gadolinium (GSO) and lutetium (LSO) oxyorthosilicates have been studied in different photonics applications [1][2][3][4], however the interest of researchers has progressively been directed towards mixed oxyorthosilicates of lutetium and gadolinium (LGSO) [5][6][7][8] due to three important reasons [9][10][11].…”

The Influence of Oxygen Vacancies on Luminescence Properties of Na3LuSi3O9:Ce3+

“…1 In many cases, basic scintillators require high density, high light yield, good energy resolution, and fast response time. 2 To meet these requirements, many cerium-doped silicate based scintillators have been developed, such as, Lu 2 SiO 5 :Ce 3+ (LSO), 3 Lu 2(1-x) Y 2x SiO 5 :Ce 3+ (LYSO), 4,5 Gd 2 SiO 5 :Ce 3+ (GSO), 6 and Lu 2 Si 2 O 7 :Ce 3+ (LPS). 7 These oxyorthosilicates and prosilicates show high light-yield and fast decay properties.…”
