Enhancement of light extraction from the LED using PDMS-ZnO quantum dots layer

Extraction of efficient light from the light-emitting diodes (LEDs) is an important and crucial factor for the solid-state lighting technology. In the present work, the performance of light extraction of the synthesized zinc oxide quantum dots (ZnO-QDs) incorporated with polydimethylsiloxane (PDMS) is studied in detail. The synthesized ZnO QDs are characterized using XRD, SEM, UV-Vis Spectroscopy and their light extraction performance is examined using quantum dots coated glass surface above the light emitting diodes (LEDs). The experimental results of the light extraction are also compared with the simulating results for more understanding. The light extraction properties of the ZnO QDs may be recommended for mass production and industrial application.
