Many studies to enhance broadband light absorption rate have been attracting intense interests as a matter of improving optoelectronic devices performance, such as solar cells and photodetectors. Spectral conversion technologies via downshifting nanoparticles are applied to broaden optical absorption wave width. In the case of ultraviolet light absorption field, downshifting luminescence abilities of quantum dots (QD), as well as fluorescent dyes, are good methods to increase the light absorption rate. Traditionally, QD in flim form is used as a downshifting material, but it has a disadvantage such that the efficiency improvement is limited. In this study, by using Layer-by-Layer(LBL) technique, we have QD adsorbed on the surface of optical nano-spherical cavity resonators, known as whispering-gallery mode(WGM) in order to amplify absorption and emission of light simultaneously. This QD-WGM bead’s light trapping capability in wide-length frequencies can be widely used in solar cells, photodetectors, or nano-lasing applications.
