Characterization and optical properties of ZnGa2O4:Eu3+ nanophosphor grown by hydrothermal method

Concentration and pump power-mediated color tunability, optical heating and temperature sensing via TCLs of red emission in an Er3+/Yb3+/Li+ co-doped ZnGa2O4 phosphor

“…57 However, sharp and narrow band emissions are observed in the presence of rare earth ions, such as Er 3+ , Ho 3+ , and Eu 3+ in ZnGa 2 O 4 phosphors. [58][59][60][61] This host is neutral under NIR illumination. When the Er 3+ /Yb 3+ ions are co-doped in the ZnGa 2 O 4 host, it gives intense red UC emission alongwith weak green emission.…”

Template-free synthesis, characterization, growth mechanism and photoluminescence property of Eu(OH)3 and Eu2O3 nanospindles

“…Rare earth metal oxides have been widely applied in various fields, such as high-performance luminescence devices, biochemical applications, catalysts and other functional materials, due to the electronic, optical and chemical characteristics arising from the electron transitions within the 4f shell [7][8][9][10][11]. The luminescence of Eu 3+ is important and interesting because the major emission band at ∼611 nm (red) is one of the three primary colors [11].…”

Luminescence of sensitive materials: towards new optical sensing

“…Because it has been demonstrated that the inversion rate is strongly linked to the experimental conditions [16][17][18][19][20], we propose here to use a Pechini synthesis to have access to a large crystallite size distributio n to impact the  ratio [3]. To control the inversion factor of doped ZnAl 2 O 4 materials may be of great interest especially when the luminescent properties are affected by the location of the emitting center, the crystal field strength .…”
