Abstract
A composite oxide contains oxides of aluminum, strontium, cerium, lanthanum, and manganese. A light emitting aspect of the composite oxide when the composite oxide is irradiated with a first electromagnetic wave having a wavelength not longer than 300 nm is different from a light emitting aspect of the composite oxide when the composite oxide is irradiated with a second electromagnetic wave having a wavelength longer than 300 nm.
Claims9
A composite oxide comprising:
- a body formed of oxides of aluminum, strontium, cerium, lanthanum, and manganese,
- wherein a light emitting aspect of the body when the body is irradiated with a first electromagnetic wave having a wavelength not longer than 300 nm is different from a light emitting aspect of the body when the body is irradiated with a second electromagnetic wave having a wavelength longer than 300 nm,
- wherein the body is one of a sintered body or a paste.
An ultraviolet detection device comprising:
- a ceramic substrate;
- and
- a composite oxide that is disposed on the ceramic substrate and contains oxides of aluminum, strontium, cerium, lanthanum, and manganese,
- wherein the composite oxide emits light when the composite oxide is irradiated with a first electromagnetic wave having a wavelength not longer than 300 nm, and does not emit light when the composite oxide is irradiated with a second electromagnetic wave having a wavelength longer than 300 nm.
