Improved Performance of Organic Light-Emitting Transistors Enabled by Polyurethane Gate Dielectric [PDF]
ACS Appl. Mater. Interfaces 2023, 15, 28, 33809-33818, 2023 Organic light-emitting transistors (OLETs) are multifunctional optoelectronic devices that combine in a single structure the advantages of organic light emitting diodes (OLEDs) and organic field-effect transistors (OFETs). However, low charge mobility and high threshold voltage are critical hurdles to practical OLETs implementation.

Low-Threshold and Narrow Linewidth Diffusive Random Lasing in Rhodamine 6G Dye-Doped Polyurethane with Dispersed ZrO$_2$ Nanoparticles [PDF]
J. Opt. Soc. Am. B 31, 2363-2370, (2014), 2015 We report on low-threshold and narrow linewidth intensity feedback random lasing in Rhodamine 6G dye-doped polyurethane with dispersed ZrO$_2$ nanoparticles. Depending on the dye/particle concentration, the lasing threshold is (6.8--15.4) MW/cm$^2$ and the linewidth is (4--6) nm. The lasing threshold as a function of nanoparticle concentration is found
