Abstract
An ultraviolet detection material includes a composite oxide including aluminum, strontium, cerium, lanthanum and manganese, and a glass having a softening point of 900° C. or lower. The ultraviolet detection material is not excited by an electromagnetic wave having a wavelength longer than 310 nm and is excited by an electromagnetic wave having a wavelength equal to or shorter than 310 nm, thereby emitting light having a peak of an emission wavelength in 480 nm or longer and 700 nm or shorter.
Claims6
An ultraviolet detection material comprising:
- a composite oxide including aluminum, strontium, cerium, lanthanum and manganese;
- and
- a glass having a softening point of 900° C. or lower,
- wherein the ultraviolet detection material is not excited by an electromagnetic wave having a wavelength longer than 310 nm and is excited by an electromagnetic wave having a wavelength equal to or shorter than 310 nm, thereby emitting light having a peak of an emission wavelength in 480 nm or longer and 700 nm or shorter,
- the composite oxide has SrAl12O19 as a main phase and Al2O3 as a sub-phase in a crystal phase, and
- cerium, lanthanum and manganese are present in the composite oxide in such a form that they are not detected by an X-ray diffraction.
