20.500.12556/DKUM-64660 FOTOLUMINISCENČNE IN ELEKTRIČNE LASTNOSTI PLASTOVITIH STANATOV Srn+1SnnO3n+1(n = ∞, 1 IN 2) DOPIRANIH Z LANTANOIDI PHOTOLUMINESCENT AND ELECTRICAL PROPERTIES OF RARE EARTH DOPED LAYERED STANNATES Sr n+1 Sn n O 3n+1 (n= ? , 1 in 2) Namen mojega diplomskega dela je bil sintetizirati in preučiti različne multifunkcionalne spojine, ki vsebujejo Sn. Dodatni namen je bil boljše razumevanje procesa sol-gel v povezavi s Sn spojinami. Glavna motivacija te raziskave je bilo odkrivanje narave in lastnosti zemeljsko alkalijskih stanatov z dodanimi Eu3+ ioni in pri tem iskanje novih anorganskih nosilcev za učinkovito lantanidno vcepitev. Iz tega razloga so bile formulirane sledeče naloge: -Predlagati nov sintetični pristop k pripravi enotnih SnO2 filmov, kateri izvirajo iz čiste raztopine, ki ne vsebuje ionov, ki bi se vmešavali, je v nevtralnem mediju in uporablja vodo kot topilo. Tudi karakterizacija Sn(IV) gel prekurzorja. -Predlagati nov in trpežen sintetični pristop za pripravo zemeljsko alkalijsko kovinskih Sr stanatov z vodno sol-gel metodo. -Raziskati fotoluminescenčne lastnosti Eu3+ z dodanimi zemeljsko alkalijskimi stanatnimi fosforji, pripravljenimi z metodo sol-gel. -Preučevanje nanostrukturiranih keramik Srn+1SnnO3n+1 (n = ∞, 1 in 2) The main aim of my bachelor's thesis was to synthesize and investigate different multifuncional compounds, that contained Sn. The additional aim was better understand the sol-gel processing route to these multifunctional tin based compounds. Moreover, the key motivation of this study was investigation of the nature and properties of the alkaline earth metal stannates doped with Eu3+ ions searching of novel suitable inorganic hosts for successful lanthanide incorporation. For this reason there were formulated tasks as follows: -To suggest a novel synthetic approach for the preparation of uniform SnO2 films, derived from highly pure solutions containing no interfering counter-ions in neutral medium using innocuous H2O as a solvent. To characterize deeply the citrato peroxo Sn(IV) precursor gel as well. - To propose a novel and versatile synthetic approach for the preparation of alkaline earth metal Sr stannates via aqueous sol-gel method. - To investigate photoluminescence properties of Eu3+ doped earth metal stannate phosphors prepared by sol-gel method. -Studying nanostructure ceramics Srn+1SnnO3n+1 (n = ∞, 1 in 2) sol-gel zemeljsko alkalijske spojine stanati sol-gel alkaline earth compounds stannates true true false [A.
