To provide an oxide (an oxygen acid salt, an oxygen acid salt halide, a double oxide and a complex oxide) to which zirconium or hafnium and manganese are added, capable of efficiently emitting fluorescence of a visible region of a wavelength of 390-750 nm when the oxide is excited by light of a vacuum ultraviolet region such as resonance line emission of 147 nm of a xenon atom, and which is expected to be applied to a fluorescent material such as a cathod-ray lamp for which mercury is not used.
The oxide is the oxygen acid salt, the oxygen acid salt halide, the double oxide or the complex oxide containing Zr or Hf in a ratio of 0.001 atomic% or more and 10 atomic% or less based on total atoms, and Mn in a ratio of 0.001 atomic% or more and 5 atomic% or less based on total atoms.
