Pressure effects on the cooperative emission of Yb 3+ : Y 2 Si 2 O 7 nano-powders

Flexible Scintillation Silica Fiber with Engineered Nanocrystals for Remote Real-Time X-ray Detection

“…The relationship between the luminescence lifetime and the size of the YPS nanocrystal is shown in Figure c. The increased lifetime can be explained by the decrease in the nonradiative relaxation and the increase of excited electrons from the ET of Ce 3+ ions. , Moreover, the nonradiative relaxation of Tb 3+ ions in NCFs would be lower with larger crystallite sizes owing to the small phonon energy of the YPS crystal lattice. , Therefore, we concluded that the luminescence efficiency of Tb 3+ ions at 542 nm increased with the formation of YPS nanocrystals in NCFs. Furthermore, the possible microstructures of Ce 3+ and Tb 3+ ions in NCF0 and NCF4 are also shown in the inset of Figure c.…”

Concentration and Cyrstalline Phase Effects on the Spectroscopic Properties of Sol-Gel Synthesized Er³⁺:Y₂Si₂O₇ Nanopowders

“…Rare earth elements (RE) doped, co-doped and tridoped Y2Si2O7 are crucial nanophosphors for lasers, light emitting diodes (LED), white LED and plasma display panel applications [13][14][15][16]. Although, various rare earth-activated yttrium orthosilicates have been studied a lot [17][18][19][20][21][22][23][24][25][26][27][28], there have been a few studies reported on the Er 3+ : Y2Si2O7. Diaz et al analyzed the luminescence properties of Y2Si2O7 : Dy phosphors prepared by a new pressureless hydrothermal route.…”

“…In our former studies, we have discussed the structural and spectroscopic properties of Y2Si2O7 : Nd and Y2Si2O7 : Yb phosphors [26,27] and the upconversion properties of Y2Si2O7 : Yb, Er nanophosphors obtained by sol-gel technique [28].…”

Magnetic effect on the phase properties of neodymium-activated yttrium disilicate nanomaterials

“…However, researchers focused on the optical spectroscopy properties of yttrium disilicates (Y 2 Si 2 O 7 ) [5][6][7][8][9][10][11][12][13] and no extensive study on the magnetic properties of yttrium disilicates when activated with neodymium has been observed in the literature. In this study, we first report on the magnetic properties of nanocrystalline α , γ , and δ polymorphs of yttrium disilicate (Y 2 Si 2 O 7 ) prepared by the sol-gel method.…”
