FIG. 7A shows a relationship of the spectral overlaps (A or B) for blue (or green) incident lights with a UV-Vis absorption spectrum of luminescent nanostructures versus a first absorption peak wavelength of luminescent nanostructures (Abs. Peak Position of QD) (nm), which is obtained by considering the results of UV-Vis absorption spectroscopy analysis for the luminescent nanostructures prepared in Examples and Comparative Examples. In FIG. 7A, “QD-B_OLED” is for the spectral overlap A (a.u., arbitrary unit) and “QD-G_OLED” is for the spectral overlap B.
FIG. 7B shows a relationship of the spectral overlap ratio (B/A) versus a first absorption peak wavelength (Abs. Peak Position of QD, nm).
FIG. 8 shows the results of measuring light conversion rates and absorbances of the display panels of examples and comparative examples, respectively.
FIG. 9A schematically shows a pattern forming process using the composition of an embodiment.
FIG. 9B schematically illustrates a pattern forming process using the ink composition of an embodiment.
