Low-temperature stearic acid sol–gel synthesis of α-Al2O3 quantum dots and its optical properties
Quantum dots of α -Al 2 O 3 were synthesized by the stearic acid sol–gel synthesis. The prepared material is characterized through XRD, FTIR, and TEM, for structural studies, and optical investigation is done through UV–Vis and FL spectra analysis. XRD analysis shows that the crystalline α -Al 2 O 3...
