Photoluminescence enhancement of Gd2Zr2O7:Eu3+ red phosphor sensitized by co-doped Al3+ ions

Dependence of Luminous Performance on Eu3+ Site Occupation in SrIn2(P2O7)2: The Effect of the Local Environment

“…4−6 Among three-color phosphors, the red component plays an important role in realizing high colorrendering illumination and super precision display. 7 However, these red phosphors developed currently have problems such as poor thermal stability and inferior light efficiency, which hinder their application and development in WLEDs. 8,9 Therefore, more effort is needed to develop high-performance red phosphors.…”

“…In the past few years, researchers at home and abroad have devoted abundant time and energy to the improvement of the luminous performance of white light-emitting diodes (WLEDs). − The research on RGB phosphors that could be effectively activated by blue or near-ultraviolet (NUV) has increased significantly. − Among three-color phosphors, the red component plays an important role in realizing high color-rendering illumination and super precision display . However, these red phosphors developed currently have problems such as poor thermal stability and inferior light efficiency, which hinder their application and development in WLEDs. , Therefore, more effort is needed to develop high-performance red phosphors.…”

Uranium-Sensitized Luminescence Enhancement in Li2B4O7:U6+,Eu3+ and Potential Application towards Color-Tunable Phosphors and Actinide Sensor

“…Previously, researchers have used Al 3+ , Mn 2+ , and Bi 3+ for sensitizing the europium luminescence. − Since these ions involve s and d electrons, there is always an energy mismatch between Eu 3+ and these ions, so efficient energy transfer may not happen despite their good absorption in the blue and near-UV regions. Utilizing Ce 3+ as a sensitizer for Eu 3+ is not feasible due to quenching through metal-to-metal charge transfer (MMCT) .…”

Design of need-based phosphors and scintillators by compositional modulation in the ZnGa2−xAlxO4:Cr3+ spinel: pure compound versus solid solutions

“…22 In fact, it has been found to induce almost ∼600% rise in the emission intensity of the Gd 2 Zr 2 O 7 :Eu 3+ phosphor by acting as a sensitizer. 23…”

“…22 In fact, it has been found to induce almost B600% rise in the emission intensity of the Gd 2 Zr 2 O 7 :Eu 3+ phosphor by acting as a sensitizer. 23 As far as Al 3+ -substituted ZGOC is concerned, not many reports are there in the literature. Zhang et al have observed increased deep red PL intensity of ZGOC nanoparticles and the same has been ascribed for the tunneling of more Cr 3+ at octahedral sites in the presence of Al 3+ .…”
