An embodiment of a luminescent borate includes a host borate that has a B9O16-comprising crystal lattice. Neodymium and/or ytterbium are present within the host borate, and one or more substitutable elements are optionally present along with the neodymium and/or ytterbium within the host borate. The one or more substitutable elements are different from neodymium and ytterbium. ## Claims ### Claim 1 A luminescent borate comprising: a host borate having a B9O16-comprising crystal lattice; neodymium and ytterbium present within the host borate; and optionally, one or more substitutable elements present within the host borate, the one or more substitutable elements being different from neodymium and ytterbium. ### Claim 2 (depends on 1) The luminescent borate of claim 1, having a density of less than or equal to 4 grams per cubic centimeter. ### Claim 3 (depends on 1) The luminescent borate of claim 1, having a formula MeXB9O16 wherein Me is selected from the group consisting of strontium, barium, or a mixture thereof; and X is a mixture of neodymium and ytterbium, optionally including the one or more substitutable elements. ### Claim 4 (depends on 3) The luminescent borate of claim 3, wherein Me is barium. ### Claim 5 (depends on 4) The luminescent borate of claim 4, wherein the one or more substitutable elements are present in the luminescent borate and include lanthanum. ### Claim 6 (depends on 3) The luminescent borate of claim 3, wherein the one or more substitutable elements are absent therefrom. ### Claim 7 (depends on 1) The luminescent borate of claim 1, wherein the one or more substitutable elements are substituted by neodymium at a first substitution percentage of at least about 20 percent, and wherein the one or more substitutable elements is substituted by ytterbium at a second substitution percentage. ### Claim 8 (depends on 7) The luminescent borate of claim 7, wherein the first substitution percentage is in a range of about 50 to about 95 percent, and the second substitution percentage is in a range of about 50 to about 5 percent. ### Claim 9 (depends on 8) The luminescent borate of claim 8, wherein the first substitution percentage is in a range of about 85 to about 95 percent, and the second substitution percentage is in a range of about 15 to about 5 percent. ### Claim 10 (depends on 1) The luminescent borate of claim 1, wherein the luminescent borate is in a form of particles with an average particle size of less than 200 microns. ### Claim 11 A luminescent material comprising: a medium; and particles of a luminescent borate dispersed in the medium, the luminescent borate comprising: a host borate having a B9O16-comprising crystal lattice; neodymium and/or ytterbium present within the host borate; and optionally, one or more substitutable elements present within the host borate, the one or more substitutable elements being different from neodymium and ytterbium. ### Claim 12 (depends on 11) The luminescent material of claim 11, wherein the particles have an average particle size of less than 200 microns. ### Claim 13 (depends on 12) The luminescent material of claim 12, wherein the medium is chosen from the group of an ink, an ink additive, a glue, a liquid, a gel, a polymer, a slurry, a plastic, plastic base resin, a glass, a ceramic, a metal, a textile, wood, fiber, paper pulp, paper, and mixtures thereof. ### Claim 14 (depends on 13) The luminescent material of claim 13, wherein the medium is ink or ink additive. ### Claim 15 (depends on 14) The luminescent material of claim 14, wherein the ink or the ink additive comprises colored dye. ### Claim 16 (depends on 11) The luminescent material of claim 11, wherein the luminescent borate has neodymium and ytterbium present within the host borate. ### Claim 17 (depends on 11) The luminescent material of claim 11, wherein the luminescent borate has a formula BaXB9O16, where Ba is barium; and X is neodymium, ytterbium, or a mixture thereof, optionally including the one or more substitutable elements. ### Claim 18 An article comprising: a security feature that includes a medium; and particles of a luminescent borate dispersed in the medium, the luminescent borate comprising: a host borate having a B9O16-comprising crystal lattice; neodymium and/or ytterbium present within the host borate; and optionally, one or more substitutable elements present within the host borate, the one or more substitutable elements being different from neodymium and ytterbium. ### Claim 19 (depends on 18) The article of claim 18, further comprising a substrate, wherein the medium is an ink that is printed on a surface of the substrate. ### Claim 20 (depends on 18) The article of claim 18, wherein the article is selected from a group consisting of an identification card, a driver's license, a passport, identity papers, a banknote, a check, a document, a paper, a stock certificate, a packaging component, a credit card, a bank card, a label, a seal, a postage stamp, a token, a liquid, a human, an animal, and a biological sample.
