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 containing oxides of aluminum, strontium, cerium, lanthanum, and manganese, wherein
- 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.
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.
An ultraviolet detection device comprising:
- a first composite oxide that contains oxides of aluminum, strontium, cerium, lanthanum, and manganese and that emits light only when the first composite oxide is irradiated with an electromagnetic wave having a wavelength not longer than 300 nm;
- a second composite oxide that contains oxides containing aluminum and cerium, and that emits light only when the second composite oxide is irradiated with an electromagnetic wave having a wavelength not longer than 400 nm;
- and
- a third composite oxide that contains oxides containing aluminum, yttrium, and cerium and that emits light only when the third component oxide is irradiated with an electromagnetic wave having a wavelength not longer than 450 nm.
