Patent number: 9841544Abstract: Disclosed are a device and a method for the design and fabrication of the device for enhancing the brightness of luminescent molecules, nanostructures, and thin films. The device includes a mirror, a dielectric medium or spacer, an absorptive layer, and a luminescent layer. The absorptive layer is a continuous thin film of a strongly absorbing organic or inorganic material. The luminescent layer may be a continuous luminescent thin film or an arrangement of isolated luminescent species, e.g., organic or metal-organic dye molecules, semiconductor quantum dots, or other semiconductor nanostructures, supported on top of the absorptive layer.Type: GrantFiled: December 8, 2014Date of Patent: December 12, 2017Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Gleb M. Akselrod, Moungi G. Bawendi, Vladimir Bulovic, Jonathan R. Tischler, William A. Tisdale, Brian J. Walker

Patent number: 8809876Abstract: Materials can be prepared in a layer-by-layer fashion on a patterned first substrate and subsequently transferred to a second substrate. The transfer step can preserve the pattern of the first substrate, such that the second substrate will bear a pattern of the transferred material. The material can be an electrostatic multilayer including a light absorbing dye, such as a J-aggregating cyanine dye.Type: GrantFiled: February 14, 2007Date of Patent: August 19, 2014Assignee: Massachusetts Institute of TechnologyInventors: Michael Scott Bradley, Jonathan R. Tischler, Vladimir Bulovic

Patent number: 8748219Abstract: The disclosed device is a solid state organic semiconductor VCSEL in which the microcavity is composed of metal and dielectric mirrors and the gain layer is only ?/2n thick. The gain layer comprises a thermally evaporated 156.7 nm thick film of the laser dye DCM doped (2.5% v/v) into an Alq3 host matrix. The microcavity consists of 2 mirrors, a dielectric Bragg reflector (DBR) sputter-coated onto a quartz substrate as the mirror through which the organic gain layer is optically excited and laser emission is collected and a silver mirror that is thermally evaporated on top of the Alq3:DCM film. The device exhibits laser action from the DCM both when the DCM molecules are excited directly at 535 nm and via Förster Resonance Energy Transfer (FRET) from the Alq3 (excited at 404 nm) with laser thresholds of 4.9 ?J/cm2 and 14.2 ?J/cm2 respectively.Type: GrantFiled: September 8, 2009Date of Patent: June 10, 2014Assignee: Massachusetts Institute of TechnologyInventors: Jonathan R. Tischler, Elizabeth R. Young, Daniel G. Nocera, Vladimir Bulovic

Patent number: 8692747Abstract: Embodiments of the present invention provide for an array, and corresponding method of forming an array, that includes a plurality of light emitting devices. The light emitting devices are disposed over a substrate, and a photodetector detects light emitted through the substrate from the light emitting devices. Further, a substantially constant brightness may be maintained in a plurality of light emitting devices disposed over the upper surface of a substrate in an array. Light emitted through the substrate from each of the light emitting devices is measured, and the voltage level applied to each of the light emitting devices is varied to maintain a substantially constant brightness level of light emitted from the light emitting devices.Type: GrantFiled: March 4, 2013Date of Patent: April 8, 2014Assignee: Massachusetts Institute of TechnologyInventors: Vladimir Bulovic, Yaakov (Jonathan) R. Tischler, Jennifer Galela
