Fotoluminescencija i Ramanova spektroskopija specifičnih kompleksnih organometalnih jedinjenja na bazi cinka, kobalta i bakra pogodnih za primenu u organskim svetlećim diodama / Photoluminescence and Raman spectroscopy of specific complexcompounds based on zinc, cobalt and copper suitable for application inorganic light emitting diodes

<p>U okviru doktorske disertacije predstavljene su elektronska i fononska struktura odabranih organometalnih materijala koji u svom sastavu imaju metale cink, kobalt ili bakar i organsko jedinjenje piridoksalaminogvanidin (PLAG). Predstavljene su realizacija i karakteristike organske svetleće diode zasnovane na najboljem od ispitivanih materijala. Urađena je detaljna analiza fotoluminescentnih spektara i njihovo razlaganje na proste komponente koristeći Lorencov model. Izvršeno je poređenje sa od ranije poznatim materijalom koji pokazuje visok stepen luminescencije. S obzirom da istraživanja vezana za organske svetleće diode uzimaju sve veći zamah i da ove diode postaju sve prisutnije u industrijskoj serijskoj proizvodnji, napravljena je detaljna analiza ove tehnologije i mehanizama koji se kriju iza nje. Urađeno je podrobno istraživanje kako na nivou elektrona u datim supstancama, tako i na nivou sloja organske svetleće diode. Na kraju je izvršena analiza rada diode sa integrisanim slojem sa materijalom koji u sebi sadrži cink i PLAG.</p> / <p>In this thesis electronic and phonon structure of specific organometallic<br />materials which have zinc, cobalt, copper metals and organic compound<br />pyridoxalaminoguanidin are presented. Implementation and characteristics of<br />organic light emitting diode based on the best material among examined<br />ones are also showed up. Detailed analysis of photoluminescence spectra<br />was done and its decomposition to its elementar components using<br />Lorentzian multipeak method. Comparison to well-known material that shows<br />high level of luminescence was implemented. In accordance to the fact that<br />research of organic light emitting diodes expands and that these diodes start<br />to be more present in industrial serial production, detailed analysis of this<br />technology and mechanisms behind it are made. Thorough research was<br />done both on electron level in these substances and organic light emitting<br />diode layer level. Finally, analysis of diode operation with integrated layer<br />made of material which includes zinc and pyridoxalaminoguanidin compound<br />is implemented.</p>
