Preparation and luminescence properties of Ca3(VO4)2: Eu3+, Sm3+ phosphor for light-emitting diodes

A vanadate-based white light emitting luminescent material for temperature sensing

“…with previously reported optical temperature sensors such as b-NaYF 4 :Nd 3+ and b-NaYF 4 :Yb 3+ /Er 3+ . The intrinsic yellow-green luminescence of vanadates has been reported in the previous work[20][21][22] . A white-light emission can be realized in this work by introducing a common Eu 3+ into a very low-cost Ca 5 Mg 4 (VO 4 )6 host.…”

“…In fact, vanadates of certain metals (Zn, Mg, Sr, Cs, K and so on) show intrinsic luminescence due to the one-electron charge transfer transition in the VO 4 tetrahedra. [20][21][22] The high-precision temperature sensing plays a key role in controlling reaction process, product performance, and safety in production. [23][24][25] Physical probes such as thermometers and thermocouples, unfortunately, have limited utilities in the situation of noncontact, small volumes, as well as high spatial resolutions.…”

A novel Sm3+ singly doped LiCa3ZnV3O12 phosphor: a potential luminescent material for multifunctional applications

“…Recently, rare-earth ion doped inorganic phosphors have attracted much attention since they can be used in a variety of applications, such as solid-state lighting, displays, and solar cells. [1][2][3][4][5][6][7][8] As is well-known, vanadate compounds usually have a broad and intense charge transfer (CT) absorption band originating from the VO 4 3À groups. Moreover, when the vanadate compounds are excited by the CT band, these materials can exhibit a broad emission band in the visible region.…”

Synthesis and Characteristics of the Zinc Effects on Eu3+ Doped (Zn,Ca)TiO3 Phosphors

“…Moreover, these emitting phosphor developed in this study can be very effectively excited at the wavelengths of 398nm. The Photoluminescence spectra shows the peak position of 618 nm [16][17][18][19][20].This single red emission characteristic indicates the excellent color purity of the phosphors. More over, red emission increases within corporation of ZnO.…”
