Lanthanum-doped ZnO quantum dots with greatly enhanced fluorescent quantum yield

The lanthanum-doped ZnO quantum dots (QDs) are synthesized by a modified sol-gel method under atmospheric conditions. The as-prepared quantum dots are characterized by X-ray powder diffraction, energy dispersion spectrum analysis and high resolution transmission electron microscopy. The optical prop...
