Preparation and properties of CdSiO3:Mn2+, Dy3+ phosphor

Concentration-dependent luminescence and energy transfer of flower-like Y2(MoO4)3:Dy3+ phosphor

“…Over the past several decades, rear earth ions (RE 3+ ) doped phosphors have attracted much attention due to their potential applications in plasma display panels (PDPs), field emission displays (FEDs), fluorescent lamps and so on [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In recent years, with the technical mature of GaN-based LEDs, it is possible to achieve solid state illumination by combining short wavelength GaN-based LED chips with tricolor phosphors.…”

Luminescence and energy transfer of Mn2+ and Tb3+ in Y3Al5O12 phosphors

“…The first is the near-UV and blue emission below 480 nm, including several peaks at 385, 419 and 439 nm, ascribed to the 5 D 3 -7 F J (J = 6, 5, 4) transitions. The second is the green and red emission above 480 nm, including several peaks at 492, 544, 593 and 629 nm, corresponding to 5 D 4 -7 F J (J = 6,5,4,3) transitions [17,18,27,28]. (For interpretation of the references to color in this text, the reader is referred to the web version of the article.)…”

“…Currently, Mn 2+ has been widely utilized in sulfides, phosphates, borates, aluminates, silicates [2][3][4][5][6], and so on, as an activator or sensitizer. The luminescence transition of Mn 2+ is parity and spin forbidden.…”

Effect of NaF flux on microstructure and thermoluminescence properties of Sm3+ doped CdSiO3 nanophosphor

“…Many metal silicates have been reported, and are being used in many areas: Mg 2 SiO 4 :Tb in thermoluminescence dosimetry of the ionizing radiations [14], Gd 2 SiO 5 :Ce in scintillation phosphors because of their relatively high-density, good light output, and fast decay time [15]. Zn 2 SiO 4 :Mn was also used as the green component in the first tri-color lamp [16], CdSiO 3 shows excellent phosphorescence property when doped with some transition metal and rare earth ions [17][18][19]. It is accepted that Sm 3 þ ions in CdSiO 3 host materials [18], can exhibit the dominant pink emission peaks under near-UV excitation.…”
