Description

Fluoride-based stress luminescent material, preparation method and application thereof
Technical Field
The invention relates to the field of novel inorganic luminescent materials, in particular to a fluoride-based stress luminescent material, a preparation method and application thereof.
Background
Stress luminescence has been discovered as early as the 16 th century, for example: the light can be emitted when earthquake or volcanic eruption occurs. Its earliest documented fact was written by Francis Bacon in 1605 in his work "The Advancement of Learning": "flashing is seen when a knife is used to quickly cut across the surface of the sugar cube". For many solid materials, they emit light when a mechanical stress is applied thereto, and this phenomenon is known as Mechanoluminescence (ML) or Tribouminescence (TL), and such a material emitting light under mechanical stress is called a stressor. The term stress luminescence was not used until 1978.
The popular saying is that: by collecting the light, the distribution of the light is converted into a distribution of stress. Stress refers to the mechanical force used to cause a material to luminesce and includes impact, tension, deformation, pressure, tension, shear, friction, fracture, and the like. In recent years, research on elastic stress luminescent materials has become a leading edge discipline. Although the conversion of mechanical stress into light distribution is quite complicated, some experiments have succeeded in applying the stress luminescence phenomenon to pressure sensors, mechanical force visualization and some other different kinds of intelligent systems, which have attracted worldwide attention, but: 1. the types of stress luminescent materials known today are very limited and are only seen in some silicates and piezoelectric materials; 2. the mechanism is not clear; 3. the trap type has not been specified.
