Spectroscopic Study of FTO/CdSe (MPA)/ZnO Artificial Atoms Emitting White Color

Light emitting diode prepared from FTO/CdSe (MPA)/ZnO artificial atom multi layers was prepared using spin coating method at room temperature. Absorption spectra reveal wide range of absorption wavelength (350-550) nm, PL spectra shows four clear peaks distribution in UV and visible spectra, Gaussian profile analysis confirm theoretical electronic transition in structure FTO/CdSe (MPA)/ZnO. Intensity of blue color was higher than green and red color due to quantum confinement effect in the structure of LED, experimental electronic transitions were corresponding to theoretical transitions.
