Structural and photoluminescence properties of ZrO2:Eu3+ @ SiO2 nanophosphors as a function of annealing temperature

Facile green fabrication of iron-doped cubic ZrO2 nanoparticles by Phyllanthus acidus: Structural, photocatalytic and photoluminescent properties

“…application remains a continuing challenge for material scientists. In general, transition metal/RE doped ZrO 2 were prepared by different methods such as polyol method, co-precipitation method, spray drying process [19][20][21]. However, these preparation methods are expensive and involve complex procedures, time consuming, require sophisticated equipments and utilize environmentally malignant chemicals and organic solvents which were toxic and not easily degraded in the environment.…”

Order and disorder effects in nano-ZrO2 investigated by micro-Raman and spectrally and temporarily resolved photoluminescence

“…Several groups have investigated the luminescence-structure relationships in Eu 3+ doped ZrO 2 with regard to the site symmetry (phase), dopant concentration, thermal treatment, surface coating, nanoparticles shape and size and so on. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] It is established that in the ZrO 2 polymorphs, the dopant site symmetry plays a major role in the radiative and nonradiative relaxation mechanisms. It is also recognized that the emission of Eu 3+ located in the tetragonal sites of ZrO 2 displays two lines with relatively close intensities, one at B590 nm (corresponding to the unresolved two allowed 5 D 0 -7 F 1 lines) and another one at B606 nm (which is the strongest among the four allowed 5 D 0 -7 F 2 lines).…”

Photoluminescence Imaging of SiO2@ Y2O3:Eu(III) and SiO2@ Y2O3:Tb(III) Core-Shell Nanostructures

“…The increase in peak intensity was mainly due to a decrease in the OH group, which commonly acts as a major luminescence quenching center. 12,20,38 The decrease in the OH stretching band of the annealed sample was confirmed by FT-IR (data not shown).…”
