Fluorescence now in use is very common, in some daily necessities, stage effects. Fluorescent stick, etc. Dudu uses fluorescence to the special material. Fluorescent this has a special nature of the material needed to produce UVLED light curing.

通过UVLED光照射产生荧光的过程在牙科诊断应用及卫生保健的其他领域引起了极大的关注。吸收了UVA光的某些分子能量迅速激发到一个很高的水平，并散发热量直至其能量减退到较低的水平。如这种转换是在相同电子自旋激发态内完成的，就会产生荧光;如是在不同电子自旋激发态内完成，就会产生磷光。低浓度状态下的发光强度与目标组织内分子浓度是呈直线比例的。正是由于这个特点，分子荧光在量化应用中是很有帮助的。自发光是一个总括，用于描述光的放射，混合了荧光和磷光，也包括诸如生物体发光之类的其他现象。许多自然界的物质都能产生荧光，包括矿物质，真菌，细菌，角蛋白，胶原质和人体的其他组织成分;这就称之为初级荧光或自身荧光。

The process of producing fluorescence by UVLED light irradiation has attracted great attention in the field of dental diagnostic application and other fields of health care. The absorption of some of the molecular energy of the UVA light rapidly excited to a very high level, and the distribution of heat until its energy decreased to a lower level. If this conversion is excited in the same electron spin state, it will produce fluorescence; such as in different electron spin excited states of the complete, will produce the phosphorescence. The intensity of light emission is proportional to the concentration of the molecule in the target tissue at low concentration. It is precisely because of this feature, molecular fluorescence in the quantitative application is very helpful. Self luminous is a blanket that is used to describe the optical radiation, mixed fluorescence and phosphorescence, also includes other phenomena such as bioluminescence and the like. Many natural substances can produce fluorescence, including minerals, fungi, bacteria, keratin, collagen and human body of other tissue components; which referred for primary fluorescence and autofluorescence.

分子散放荧光的持续时间与其被激发的长度相同，这与磷光的产生不同，当切断外部激发光源后，分子还是可以释放部分磷光。如果光释放是在光爆的一秒的百万分之一时间内发生的，这种自发光就称为荧光，反之如果光释放时间长于上述时间，就称为磷光。各种波长可激发并放射大范围的荧光团。因此，对任何荧光团来说，必定会出现吸收光谱和放射光谱重叠的现象。激发峰位和发射峰位的波长之间的差值就被称为斯托克斯位移。

Molecular diffusion and duration of fluorescence and excitation are the same length, which is different from the creation of phosphorescence, when cut off the external excitation source molecules can still release section phosphorescence. If the light is released in optical burst a second one millionth time, the self light-emitting is known as fluorescence and vice if the release time is longer than the time, phosphorescence. Various wavelengths can be excited and emit a large range of fluorescent. As a result, the absorption spectrum and the overlap of the emission spectrum are bound to be the result of the absorption spectrum and the emission spectrum. The difference between the peak position and the peak position of the emission peak is called the Stokes shift.

荧光的激发光源必须能够产生足够强度的荧光团吸收带内的光波。到目前为止，UVA光源可包括氮分子激光，氦镉激光器，高压镉灯，高压氙气灯和金属卤化物弧光灯。这些光源体积大，价格昂贵且使用寿命短。UVLED技术的先进理念，UVA发光二极管得到了发展。

Fluorescent excitation light source must be able to generate sufficient intensity of the fluorescent band absorption band of light. So far, the UVA light source can include nitrogen molecular laser, helium cadmium laser, high-voltage cadmium lamp, high-pressure xenon lamp and metal halide arc lamp. The light source is large in size, high in price and short in service life. The advanced concept of UVLED technology, UVA light-emitting diode has been developed.

如果要观察荧光，就需要使用滤光片，它可以透过荧光波长而不是激发波长。这些滤光片可以是彩色玻璃或聚合体也可以是较为昂贵的干扰滤光片，它是由绝缘材料在不同折射率的玻璃表面层层重叠制成的。光的不同波长会引发相长和相消干扰，部分光波被透射出去而其他会被折射回去。所以通常会在测量荧光的仪器上安装有干扰滤光器。

If you want to observe the fluorescence, you need to use the filter, it can be through the fluorescence wavelength and not the excitation wavelength. These filters can be stained glass or polymer can also be more expensive interference filter, it is by the glass surface of the insulating materials in different refraction rate of overlapping layers made of. The different wavelengths of light will lead to constructive and destructive interference, while the other is part of the optical transmission will be reflected back out. So it is often in the measurement of the instrument on the measurement of the interference filter.

荧光这种特殊的材质只有在黑暗的情况下才能体现其发光的一面。而在uvled光固化的作用的。使得荧光的生产变得方便快捷。也使得荧光能够更好的推广。
