Fluorescence, as the name implies, is the light emitted under the irradiation of light.
From the knowledge of atomic physics, we know that for each chemical element of the atom, there is a specific energy level structure, the electrons outside the nucleus with their own unique energy in their own fixed orbit, the inner electron in the sufficient energy of the X-ray irradiation out of the atomic nucleus of the bondage, become free electrons, we say that the atom is excited, in the excited state, at this time, the other outer electron This is when other outer electrons fill the empty space, known as a jump, while emitting energy in the form of X-rays. Since the atomic energy level structure of each element is specific, the energy of the X-rays emitted when it leaps after being excited is also specific, and is called characteristic X-rays. By measuring the energy of the characteristic X-rays, the presence of the corresponding element can be determined, and the strength of the characteristic X-rays (or the number of X-ray photons) represents the amount of that element.
Quantum mechanics tells us that X-rays are wave-particle duality and can be viewed as either particles or electromagnetic waves. The energy when viewed as a particle and the wavelength when viewed as an electromagnetic wave have a one-to-one relationship. This is the famous Planck's formula: E = hc / λ. Obviously, whether it is the determination of energy, or wavelength, can be realized on the corresponding elemental analysis, the effect is exactly the same The original imported electric refrigeration detector, can be quickly analyzed from the 11Na to 92U between all the elements, high precision, measurement time is short, it can be widely used in non-ferrous mines, iron and steel, cement, refractory materials, stainless steel, It can be widely used in non-ferrous mines, steel, cement, refractory materials, stainless steel, alloys and other fields
