Piranilidena atvasinājumu optiskās un pastiprinātas spontānās emisijas īpašības PVK matricā

2015

Organiskie materiāli ir daudzsološi dažādiem moderniem pielietojumiem, tai skaitā optiski ierosinātiem organiskajiem cietvielu lāzeriem, kuriem vajadzīgi materiāli ar augstu pastiprināšanās koeficientu un zemām ierosmes enerģijām. Vairumā organisko sistēmu šie parametri ir limitēti krāsvielu molekulu kristalizācijas dēļ. Tādēļ savienojumi ar samazinātu kristalizēšanos būtu ļoti noderīgi. Šajā darbā tika pētītas plānās kārtiņas ar jauniem plaši zināmās krāsvielas DCM atvasinājumiem PVK polimēra matricā dažādās koncentrācijās. Kārtiņām tika uzņemti fotoluminiscences spektri un veikti pastiprinātas spontānās emisijas (PSE) mērījumi. Tika novērota spēcīga koncentrācijas ietekme uz emisijas spek…
