Description
Technical field
The invention belongs to photostimulated phosphor preparation and application technologies.
Background technique
Stress irradiance (Mechanoluminescence) refers to that object (such as expansion, stretching, breaks by various stress
The effects of splitting, rubbing) the lower luminescent behavior of effect, i.e. the mechanical energy conversion process that is converted into electromagnetic light radiation energy.According to material
Deformation degree when stress irradiance is generated, stress light emitting material can be divided into destructive stress and shine and non-destructive stress hair
Light, rather than destructive stress shine again can be divided into elastic stress shine and plastic stress shine.Although shining to elastic stress
The history of the research only about 20 years of material, the unique property as possessed by elastic stress luminescent material is (such as in elastic deformation
In limit, luminous intensity and deformation quantity are directly proportional, and do not damage detection object), power-light can be made into and passed
