Near-infrared OLED has been very difficult to achieve high efficiency and stability, mainly due to material limitations. In this research, they used a method that combines a phosphor that converts orange light into near infrared and an orange OLED that has a high efficiency and stability by using a down-conversion. Through optical analysis and optimization at the down-conversion process, they finally implemented a near-infrared OLED with a near-infrared external quantum efficiency of about 14%.<\/p>\n<p>The developed light source is expected to be used for wearable healthcare, because it has the advantages of OLED flexibility and near-infrared rays with various applications.<\/p>\n<p>Congratulations!<\/p>\n<table border=\"1\" cellpadding=\"1\" cellspacing=\"1\" style=\"width: 800px\">\n<tbody>\n<tr>\n<td class=\"rtecenter\" style=\"width: 75px\">Conference<\/td>\n<td class=\"rtecenter\" style=\"width: 716px\">OSA Advanced Photonics Congress 2019<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"width: 75px\">Date<\/td>\n<td class=\"rtecenter\" style=\"width: 716px\">2019.07.29~2019.08.01<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"width: 75px\">Location<\/td>\n<td class=\"rtecenter\" style=\"width: 716px\">Hyatt Regency San Francisco Airport, San Francisco, California, USA<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"width: 75px\">Winner<\/td>\n<td class=\"rtecenter\" style=\"width: 716px\">Ph.
