“…In order to create light-emitting polymer nanocomposites, various additives have been employed to change the optical properties of polymers, in particular polymethyl methacrylate (PMMA). PMMA has been shown to be a suitable matrix for optically active additives (dopants) [8]. Luminescent species that have the capability of fluorescing and being dopants to overcome attenuation are organic dyes, quantum dots, and rare-earth (RE) ions doped in inorganic nanocrystals [9][10][11][12].…”

Organicallycoated inorganic nanoparticles were synthesized to produce photoluminescent nanocomposites based on a polymethyl methacrylate (PMMA) matrix. The nanoparticles comprised organic ligands (acetylsalicylic acid, ASA, and 2-picolinic acid, PA) attached to the lanthanum trifluoride (LaF3) host crystals that were doped with optically active terbium III (Tb3+) and synthesized using solution-based methods. The ligands were employed to functionalize the surface of Tb3+:LaF3nanocrystals to aid in dispersing the nanoparticles. In order to confirm the presence of the constituents within the inorganic-organic system, the nanoparticles were characterized by infrared spectroscopy and energy-dispersive X-ray spectroscopy. Absorption peaks observed from infrared spectroscopy for all the polymer nanocomposites loaded with organic surface treated nanocrystals exhibited peaks that were not present in undoped PMMA but were characteristic of the dopant and the ligand.

“…However, polymers exhibit inherently high vibrational energies which tend to quench many of the transitions of rare-earth ions thus limiting their application as optical materials [4]. RE ions are typically incompatible with organic polymers; although, PMMA has been shown suitable when utilized as a matrix for certain RE ion ligand complexes [5].…”

Inorganic nanoparticles doped with optically active rare-earth ions and coated with organic ligands were synthesized in order to create fluorescent polymethyl methacrylate (PMMA) nanocomposites. Two different aromatic ligands (acetylsalicylic acid, ASA and 2-picolinic acid, PA) were utilized in order to functionalize the surface of Tb 3+ : LaF 3 nanocrystals. The selected aromatic ligand systems were characterized using infrared spectroscopy, thermal analysis, rheological measurements, and optical spectroscopy. Nanoparticles produced in situ with the PMMA contained on average 10 wt% loading of Tb 3+ : LaF 3 at a 6 : 1 La : Tb molar ratio and ∼7 wt% loading of 4 : 1 La : Tb molar ratio for the PA and ASA systems, respectively. Measured diameters ranged from 457±176 nm to 150 ± 105 nm which is indicative that agglomerates formed during the synthesis process. Both nanocomposites exhibited the characteristic Tb 3+ emission peaks upon direct ion excitation (350 nm) and ligand excitation (PA : 265 nm and ASA : 275 nm).

“…Amorphous polymers such as polymethyl methacrylate (PMMA) are utilized in numerous optical applications because they are highly transparent in the visible. PMMA has been the most predominate polymer employed to date for optical purposes and has been shown to be a suitable medium for certain rare-earth (RE) ion ligand complexes [3] that generate light. While the higher attenuation of polymers, relative to inorganic glasses (e.g., silica optical fiber), limits their use to distances of less than about 1 km [4], there are still many applications for light emissive polymer fibers, films, and coatings.…”

Organic ligand surface-treated Tb 3+ :LaF 3 was synthesized in water and methanol for subsequent incorporation into polymethyl methacrylate (PMMA) via solution-precipitation chemistry in order to produce optically active polymer nanocomposites. Nanoparticle agglomerate diameters ranged from 388 ± 188 nm when synthesized in water and 37 ± 2 nm when synthesized in methanol. Suspension stability is paramount for producing optically transparent materials. Methanol nanoparticle synthesized at a pH of 3 exhibited the smallest agglomerate size. Optical spectroscopy, dynamic light scattering, transmission electron microscopy, scanning transmission electron microscopy, and zeta potential analysis were used to characterize the particles synthesized.
