Abstract: The invention is directed to a lanthamide chelate composition having a lanthamide, a charged amidate ligand, and a mono- or bidentate neutrally charged coordination compound, the composition being represented by structure I or structure II wherein Ln3+ designates lanthamide, R1 is alkyl, aryl, or heteroaryl; R2 is alkyl, aminoalkyl, aryl or heteroaryl; M is a neutrally charged monodentate coordination compound, M? is a neutrally charged bidentate coordination compound, a=1 or 2; and wherein M and M? comprise N, S, or O. It extends to the process of making the composition.

Abstract: Deposited thin-film dielectrics having columnar grains and high dielectric constants are formed on heat treated and polished metal foil. The sputtered dielectrics are annealed at low oxygen partial pressures.

Abstract: The invention is directed to a lanthamide chelate composition having a lanthamide, a charged amidate ligand, and a mono- or bidentate neutrally charged coordination compound, the composition being represented by structure I or structure II wherein Ln3+ designates lanthamide, R1 is alkyl, aryl, or heteroaryl; R2 is alkyl, aminoalkyl, aryl or heteroaryl; M is a neutrally charged monodentate coordination compound, M? is a neutrally charged bidentate coordination compound, a=1 or 2; and wherein M and M? comprise N, S, or O. It extends to the process of making the composition.

Abstract: The invention is directed to a method wherein at least a portion of a luminescent coating disposed on a surface of an article is exposed to ultraviolet light causing the luminescent coating to exhibit luminescence, detecting the luminescence, causing a comparison to be made between the luminescence and a predetermined standard, and classifying the article according to the comparison, wherein the luminescent coating has a luminescent chelate being a lanthanide and a ligand, the ligand being represented by the formula wherein R1 is alkyl, aryl, or heteroaryl; R2 is alkyl, aminoalkyl; aryl or heteroaryl.

Abstract: The invention is directed to a composition having a carrier and a luminescent chelate wherein the lanthanide chelate being a lanthanide and a ligand wherein the ligand being represented by the formula wherein R1 is alkyl, aryl, or heteroaryl; and R2 is alkyl, aminoalkyl, aryl or heteroaryl. The invention is further directed to a process for coating articles.

Abstract: The invention is directed to a composition having a lanthanide chelate being a lanthanide and a ligand wherein the ligand is represented by the formula wherein R1 is alkyl, aryl, or heteroaryl; R2 is alkyl, aminoalkyl, aryl or heteroaryl; with the proviso that R1 and R2 cannot both be phenyl, and with the proviso that R2 cannot be phenyl when R1 is alkyl.
