Persistent phosphorescent composite material |
摘要 |
The invention relates to a persistent phosphorescent ceramic composite material which is a sintered dense body comprising two or more phases, a first phase consisting of at least one metal oxide and a second phase consisting of a metal oxide containing at least one activating element in a reduced oxidation state. The invention furthermore relates to a method for the preparation of a phosphorescent ceramic composite material as defined in any of the previous claims, the method comprising the following steps: preparing a mixture of a metal oxide and a phosphor; fabricating a green body from the mixture; and heat treating the green body in a reducing atmosphere. |
