Abstract

A curing device may comprise a first array of LED's, each LED of the first array emitting radiation substantially centered at a first excitation wavelength onto a quantum dot layer, the quantum dot layer positioned above the first array of LED's and configured to partially absorb the first excitation wavelength radiation and down convert the absorbed first excitation wavelength radiation, and partially transmit the emitted first excitation wavelength radiation, wherein the down converted and the partially transmitted first excitation wavelength radiation are directed onto a radiation-curable workpiece.
