Synthesis and optical property of water-soluble ZnS:Cu quantum dots by use of thioglycolic acid

Aqueous synthesis of glutathione-capped Cu+and Ag+-doped ZnxCd1−xS quantum dots with full color emission

“…Although hydrophilic Cu-doped ZnS and ZnSe QDs have been reported, the quality of these hydrophilic d-QDs is signicantly lower than those of hydrophobic d-QDs. [35][36][37] Thus, the direct synthesis of bio-compatible and water soluble d-QDs is critically important, which can avoid the tedious ligand exchange procedures and toxic organic solvents. In addition, Ag + ions as an excellent luminescent center, have been extensively doped in bulk ZnS, forming highly luminescent Ag-doped ZnS phosphors.…”

Luminescence Properties of Ba3Si6O12N2:Eu2+Green Phosphor

“…as a promising red phosphors [1][2][3][4][5][6][7] . In this work, for high light source efficiency of green phosphor, greenemitting ternary nitride Ba 3 Si 6 O 12 N 2 :Eu 2+ phosphor was synthesized in a high frequency induction furnace under N 2 gas atmosphere at temperatures up to 1400 o C by using solid state second-step heat treatment process.…”

Luminescence Enhancement of ZnS:Cu Nanocrystals by Zinc Sulfide Coating with Core/Shell Structure

“…With its wide band gap energy of 3.67 eV at room temperature, ZnS is particularly suitable for use as luminescent host materials for a very large variety of metal dopants. Metal doped ZnS NCs, such as ZnS doped with manganese [9][10][11], copper [12,13], terbium [14,15] and europium [16,17], have been reported numerously about their structural and luminescent properties. The dopants act as recombination centers for the excited electron-hole pairs and result in strong and characteristic luminescence, and overcome a couple of intrinsic disadvantages of undoped ZnS NCs emitters [18].…”
