    Abstract: A scintillation compound, other than a rare earth silicate, can include a rare earth element that is in a divalent (RE2+), trivalent (RE3+) or a tetravalent state (RE4+). The scintillation compound can include another element to allow for better change balance. The other element may be a principal constituent of the scintillation compound or may be a dopant or a co-dopant. In an embodiment, a metal element in a trivalent state (M3+) may be replaced by RE4+ and a metal element in a divalent state (M2+). In another embodiment, M3+ may be replaced by RE2+ and M4+. In a further embodiment, M2+ may be replaced by a RE3+ and a metal element in a monovalent state (M1+). The metal element used for electronic charge balance may have a single valance state, rather than a plurality of valence states, to help reduce the likelihood that the valance state would change during formation of the scintillation compound.

The authenticating equipment comprises at least one first source of electromagnetic radiation of at least one first preselected wavelength and at least one second source of at least one second preselected wavelength which are different from each other. The radiation of the first and of the second wavelength are selected such as to cause the up-converting material upon combined radiation with said first and second wavelength to release an emission spectrum. The electromagnetic emission spectrum of said up-converting material comprises radiation of at least one wavelength which is specific for the return of at least one electron from an energy level to which the electron is raised by the combined radiation of at least said first and said second wavelength.

    Abstract: Spherical particles of fluoride up-converter phosphors having a particle size of 1 micron and less can be made from their corresponding precursor hydroxycarbonate particles by heating the hydroxycarbonate particles in an oxygen-containing atmosphere to convert the hydroxycarbonate to the corresponding oxide but without changing the size and shape of the particles, and then heating the phosphor oxide particles to their corresponding fluoride particles by heating in SF6, at a temperature that will crack the SF6 but will not change the size or shape of the phosphor particles.
