Thin films of Cu(II)-o,o′-dihydroxy azobenzene nanoparticle-embedded polyacrylic acid (PAA) for nonlinear optical applications developed by matrix assisted pulsed laser evaporation (MAPLE)

Laser printing of azo-derivative thin films for non-linear optical applications

“…In our previous work, the use of a laser technique had been aimed towards demonstrating thin film growth [12][13][14], and we have shown that matrix-assisted pulsed laser evaporation (MAPLE) is suitable for processing complex chemical compounds. The studied material, namely 1-phenyl-3-methyl-4-(1'-azo-2'-sodium carboxylate)-pyrazole-5-one (a pyrazolone derivative, further referred to as "azo") exhibits important non-linear optical properties, in bulk (powder) form, as well as in MAPLE grown thin films [14].…”

“…Further details on the MAPLE procedure are given elsewhere [11][12][13][14][17][18][19][20][21]. In order to reduce traces of solvent and its potential influence on the optical and morphological properties, the films were annealed at 60⁰C for 9 hours, following deposition.…”

Thermal behavior and matrix-assisted pulsed laser evaporation deposition of functional polymeric materials thin films with potential use in optoelectronics

“…For this study, thin films of poly(vinyl chloride)-(PVC), poly(acrylic acid)-(PAA), and polyaniline-(PAni) were deposited by a matrix-assisted pulsed laser evaporation (MAPLE) technique, as choice materials since they find immediate applications in organic electronics (PAni) [27,31], as embedding matrices (PAA) [20,32], as scaffolds, biocompatible substrates or coatings in medical equipments (PVC) [30,33]. The thermal behavior of these polymers was investigated as it represents an important issue for the stability of the thin films.…”

“…The increasing demand for new and permanently improved electronic consumer products requires higher functionality in reduced dimensions [5]. Organic materials can be used as solid matrices [20], in electrochromic devices, energy conversion and storage units, such as: (micro)batteries [24] and fuel cells [25], photochemical solar cells [26], supercapacitors [27], but also in sensors [28], organic thin film transistors (OTFTs) [29], transducers, biosensitive interfaces [30], etc.…”

“…Different thin film deposition and growth techniques were used, including conventional ones, such as: dip-coating, drop-casting, spin-coating, but also more sophisticated ones, such as: electron gun evaporation, plasma assisted chemical vapor deposition techniques [13,14], and laser-assisted techniques [15][16][17][18][19][20][21][22][23]. The increasing demand for new and permanently improved electronic consumer products requires higher functionality in reduced dimensions [5].…”
