Changes of fluorescent spectral features after successive rare earth doping of gadolinium oxide powders

Microwave-assisted one-pot synthesis of water-soluble rare-earth doped fluoride luminescent nanoparticles with tunable colors

“…Kuznik et al investigated fluorescent properties of gadolinium oxide powders doped with different rare earth ions (Er 3+ , Tb 3+ , Dy 3+ ). They found that singly doped Er 3+ sample gave stronger luminescence signals and others showed significantly larger decay lifetimes [20]. …”

Brownish red emitting YAG:Ce3+,Cu+ phosphors for enhancing the color rendering index of white LEDs

“…For this reason, the white LEDs have lower color rendering index [5]. Many researchers had made great efforts to develop new LED phosphors including silicates, aluminates, sulfides, phosphates, borates, nitrogen-oxides, oxides, nitrides, molybdates host [6][7][8][9][10][11][12][13][14][15][16][17]. But these materials have some shortcoming more or less, such as bad physical and chemical stability.…”

Luminescence enhancement of CaMoO4:Eu3+ phosphor by charge compensation using microwave sintering method

“…With their advantages of high efficiency, long lifetime, and non-pollution, LEDs have been widely applied in lighting and display devices, including plasma display panel, field emission display, white light diode, etc. [4][5][6][7]. However, white LEDs with GaN based blue-emitting chips and yellow-red phosphors have poor color rendering index due to the deficiencies in red emission [8] in current market.…”
