摘要： A mechanically flexible array of optically pumped vertical cavity surface emitting lasers, fabricated using spin coating. The array uses InGaP colloidal quantum dots as an active medium and alternating polymer layers of different refractive indices as Bragg mirrors. Enhanced spontaneous emission is produced. The flexible array can be peeled off a substrate, producing a flexible structure that can conform to a wide variety of shapes, and having an emission spectrum that can be mechanically tuned. The flexible array can be used to create a flexible infrared light bandage.

摘要： A spin-coated polymer microcavity for light emitters and lasers producing enhancement of spontaneous emission rate from colloidal CdSe/ZnS core/shell quantum dots embedded in a one dimensional polymer microcavity structure at room temperature. The polymer microcavity structures are fabricated using spin coating. Alternating layers of polymers of two different refractive indices were stacked to form the Distributed Bragg reflectors (DBRs). To achieve high reflectivity, the polymers for the DBR structures were chosen so that they have a relatively high refractive index ratio. The high and low refractive index polymers chosen were poly-N(vinylcarbazole) (PVK) and poly acrylic acid (PAA), with refractive indices of 1.683 and 1.420 at 600 nm, respectively. Thin films of quarter wavelength thickness of the two polymers are alternately spin coated on a glass substrate to make the DBR structures. Greater than 90% reflectivity is obtained using ten periods of the structure. A PVK cavity layer of λ thickness embedded with CdSe/ZnS core/shell quantum dots is sandwiched between two of these DBRs to form the entire microcavity structure. The bottom and top DBRs comprise ten and five periods, respectively.
