Abstract

The provided intensifying luminescent device comprises: a luminescent assembly and a transparent package layer contained resin and intensifying fluorescent material with chemical general formula as following. Wherein, R is one of alkoxy- substituted phenyl, substituted or un-substituted anthryl / pyrene / 9, and 10-anthraquinone.

Description

technical field [0001] The present invention relates to a light-emitting device, more particularly, the invention relates to a light-enhancing light-emitting device. When the light is turned on, the light-enhancing fluorescent material can be excited to emit visible light with high brightness and no moon halo, black, yellow and other color spots. Background technique [0002] Fluorescent materials are widely used and are closely related to people's lives. They are mainly used in detergents (including washing powder, soap, etc.), paper, various textile fibers and others (such as plastics, grease, paint, etc.), but fluorescent materials are used in non-textiles. The application is far greater than the application directly on textiles. With the development of science and technology, the use of fluorescent materials is expanding, such as fluorescent detection, lasers, light-emitting devices, etc., so fluorescent materials have broad development prospects, and the role played by...
