Size-dependent luminescence in Y2Si2O7 nanoparticles doped with Ce3+ ions

Influence of vinyltriethoxysilane concentration on structural and luminescent characteristics of cerium doped yttrium based silicate phosphors

“…It was found that, X1-Y 2 SiO 5 phase is transformed into X2 phase at around 1190 1C [9,10]. On the other hand, α-Y 2 Si 2 O 7 phase begins to crystallize at $ 1000 1C and totally converts into β form at 1400 1C [11,12].…”

“…It was given a great attention to the study that shows the role of different preparative conditions (concentration and type of activators, firing temperature etc.) on the phosphor's characteristics [11,18]. Improvements on the luminescent characteristics and morphology of silicate phosphors can be done using mineralizing agents like: NaCl, BaF 2 , H 3 BO 3 or Li 2 SO 4 [18,19,20].…”

Size effect in luminescent properties of LiNdP4O12 nanocrystals

“…The second results in the change of the effective refractive index increasing luminescence decay with the reduction of the average grain size [3][4][5][6]. The size effect in inorganic phosphors has been investigated by many authors [7][8][9][10][11][12][13]. However, phenomenon associated with the size effect are still not well understood.…”

Spectroscopic and structural properties of polycrystalline Y 2 Si 2 O 7 doped with Er 3+

“…These hosts exhibit also a minimal effect of nuclear spins of the constituent elements which results in narrow homogeneous emission lines of the dopant RE ions [7,8,9]. Y 2 SiO 5 (YSO) doped with Ce-ions (YSO:Ce 3+ ) is one of the best low-voltage phosphors for field emission displays due to its high efficiency, colour purity and stability [2,3,[9][10][11]18], YSO:Tb 3+ is considered one of the best green emitting cathodoluminescent phosphors [1] and YSO:Eu 3+ as a promising phosphor for high resolution applications [13][14][15]19]. Moreover in more recent years, erbium compounds [20][21][22][23][24] and erbium doped yttrium silicates [25][26][27] have attracted considerable attention also as active medium of small-size on-chip amplifiers and lasers around the telecom wavelength in silicon photonics.…”

“…Yttrium silicates are among the most interesting hosts for rare-earth (RE) ions, which substitute easily Y 3+ ions [1][2][3][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. These hosts exhibit also a minimal effect of nuclear spins of the constituent elements which results in narrow homogeneous emission lines of the dopant RE ions [7,8,9].…”
