Light up-conversion from near-infrared to blue using a photoresponsive organic light-emitting device

@article{citeulike:587531, abstract = {A photoresponsive organic light-emitting device combining blue-emitting organic electroluminescent (EL) diode with titanyl phthalocyanine as a near-infrared (IR) sensitive layer was fabricated. By irradiating near-IR light to the device, blue emission occurred in the lower drive voltage (between 5 and 12 V). The result indicates that the device acts as a light switch and/or an up-converter from near-IR light (1.6 eV) to blue (2.6 eV). The EL response times of rise and decay using a near-IR light trigger were 260 and 330 \µs, respectively. At a higher voltage (above 12 V), enhancement of blue emission was observed with near-IR light irradiation. The ON/OFF ratio reached a maximum of 103. \©2002 American Institute of Physics.}, author = {Chikamatsu, Masayuki and Ichino, Yoshiro and Takada, Noriyuki and Yoshida, Manabu and Kamata, Toshihide and Yase, Kiyoshi }, citeulike-article-id = {587531}, comment = {pdf}, doi = {http://dx.doi.org/10.1063/1.1495881}, journal = {Applied Physics Letters}, keywords = {oled, opd, tiopc}, number = {4}, pages = {769--771}, posted-at = {2006-04-15 12:35:21}, priority = {2}, publisher = {AIP}, title = {Light up-conversion from near-infrared to blue using a photoresponsive organic light-emitting device}, url = {http://dx.doi.org/10.1063/1.1495881}, volume = {81}, year = {2002} }
