Photoluminescence Characteristics of Nanocrystalline ZnGa₂O₄Phosphors Obtained at Different Sintering Temperatures

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

“…The obtained results are similar with that for bulk crystals and nanocrystals [4,26] with the same chemical formula.…”

“…As an important semiconductor, with wide band gap of 4.4-4.7 eV, zinc gallate exhibits potential advantages of the superior thermal and chemical stability under electron bombardment in comparison with sulfide phosphors. It has attracted considerable attention and is may be a good candidate for light emitting diodes, photodetectors, photocatalysis, low voltage and multicolor-emitting phosphors [1][2][3][4][5].…”

Red, Green, and Blue Luminescence from ZnGa2O4 Nanowire Arrays

“…[8][9][10][11] It is anticipated that when the phosphors are made into nanocrystals, the density of emission sites would be dramatically increased, which may lead to high-brightness and high-definition display. 12 Considerable efforts have been spent in recent years to fabricate ZnGa 2 O 4 nanowires and their arrays. [13][14][15] Bae et al synthesized aligned ZnGa 2 O 4 nanowires by thermal evaporation of ZnO-Ga powders using Au as a catalyst.…”

“…Zinc gallate (ZnGa 2 O 4 ), a ternary spinel material with a band gap of 4.4−4.7 eV, has shown excellent potential for incorporation in future display system because of its prominent blue emission, high chemical and thermal stability, and good cathodoluminescence characteristics at low-voltage. , ZnGa 2 O 4 is naturally a very promising blue-emitting phosphor . It can also act as an excellent host material for high luminance multicolor-emitting phosphors when doped with appropriate activators: Mn-activated ZnGa 2 O 4 (ZnGa 2 O 4 :Mn 2+ ) for green emission , and Cr-doped ZnGa 2 O 4 (ZnGa 2 O 4 :Cr 3+ ) for red emission. , ZnGa 2 O 4 phosphors (with or without doping) were usually used in the form of thin films. − It is anticipated that when the phosphors are made into nanocrystals, the density of emission sites would be dramatically increased, which may lead to high-brightness and high-definition display …”

Facile route to straight ZnGa2O4 nanowires and their cathodoluminescence properties

“…As an important semiconductor with wide band gap of 4.4-4.7 eV, zinc gallate (ZnGa 2 O 4 ) has attracted considerable attentions and is maybe a good candidate for light emitting diodes, photodectors, photocatalysts, low-voltage and multicolor emitting phosphors [5][6][7][8][9]. Up to now, the syntheses and their physical properties of ZnGa 2 O 4 nanowires have attracted more attentions and been successfully performed.…”
