Thin-Film Deposition of Polymers by Vacuum Degradation

“…Gritsenko et al ,− investigated phthalocyanine-filled polymer films, obtained either by dye co-evaporation with PTFE from dual sources or with PCTFE by a composite powder pellet. H 2 Pc, VOPc, ZnPc, CoPc, and CuPc were used.…”

Nanoclusters in polymer matrices prepared by co-deposition from a gas phase

“…Additional band at 543 nm appeared. RF-discharge treatment of Sq vapor during LBE resulted in film deposition with the spectrum similar to that for thermally evaporated film [53,55,56]. Hence, LBE promotes dye cluster formation, while mild RF-discharge and dilution in polymer matrix works in the opposite direction.…”

“…Gritsenko et al investigated the characteristics of films obtained by CO 2 laser beam evaporation (LBE) of powder pellets composed of dye mixed with PCTFE or PS [35,36]. In contrast to films deposited by evaporation, the absorption spectrum of VOPc film deposited by LBE at room temperature exhibited a maximum at 825 nm.…”

“…Sq -PPS contains only one type of clusters with round shape and various sizes (Fig. 16) [43,53,54]. It should be noted, that pure allyl -Sq could not be deposited by LBE due to its decomposition, while OHSq can be deposited with rates up to 100 nm/s.…”

Dye-filled polymer film formation in vacuum

“…The absorption spectrum of VOPc films deposited by TE has three maxima: -at 655 nm, 720 nm and a small one at 820 nm, while the spectrum of the film, deposited by LBE, has the most intensive band at 825 nm 7,8 intensity. 1%VOPc+PCTFE pellet LBE resulted in film formation with most intensive 825 nm band, less intensive 595 nm and 715 nm bands.…”
