摘要: In a method for vapor-depositing a substrate with a layer of a needle-shaped x-ray fluorescent material containing at least one alkali metal, alkali halogenide phases and an alkali halogenide are mixed in a vapor phase and are vapor-deposited on the substrate. A needle-shaped fluorescent material is thereby produced having the formula ( ( M ′ + H ′ - ) a ( M ′′ + H ′′ - ) ( 1 - a ) ) k : ( M x ′ + S y z + H x ′ - H z * y ′′′ - ) b ( M x ′′ + S y z + H x ′′ - H z * y ′′′ - ) c ( M x ′ + S y z + H x ′′ - H z * y ′′′ - ) d ( M x ′′ + S y z + H x ′ - H z * y ′′′ - ) e wherein M+ is at least one metal ion from the group Na, K, Rb and Cs, H− is at least one halogenide from the group F, Cl, Br and I and Sz+ is at least one lanthanide ion from the group La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb or Lu.
