Rare earth up-conversion luminescence technology was shortlisted for the state technological invention award

The Ministry of Science and Technology released the preliminary evaluation results of the state science and technology awards, and "the establishment and multi-field application of real-time detection system based on rare earth nanoscale transmitting light technology" recommended by the Chinese medical association was shortlisted for the second prize. The project was developed by a project team supported by the academy of military medical sciences, Shanghai institute of optics and precision mechanics, Shanghai keyan optoelectronic technology co., LTD and Beijing...

What is acrylic ( plexiglass ) glow in dark board

Luminous plexiglass is also a kind of fluorescent plexiglass, which is prepared by mixing luminescent powder and plexiglass. Why is this plexiglass emitting light all night? The so-called luminous board is also classified as plexiglass in the classification, and it is mixed with luminous powder in the production process of plexiglass, and it is named because it can emit light in the dark. So what kind of plexiglass can achieve luminescence? It turned out that this benefited from the raw materials...

About Invisible security printing

  It is a new type of optical imaging technology which integrates micro and nano graphic design, optical interference, stereoscopic imaging and other modern high precision manufacturing technologies into a comprehensive anti-counterfeiting printing technology Confidentiality is strong Invisible anti-counterfeiting "integrated into the printed matter, the appearance is not visible or a flat color block, security anti-counterfeiting information is not visible, need a special corresponding lens, ultraviolet light or xenon lamp to check and verify; And security information can be designed in multiple...

Luminous road decorated with glow in dark stones

A new planner inspired by van gogh's famous painting "starry night", planned a "luminous bicycle path", high, low power consumption, long life, fast start, small power, no stroboscopic, not easy to produce visual fatigue and other advantages, LED; Floor tile lamp is a product often used in lighting of night scene in recent years, the surface cover of the lamp body that USES stainless steel plate one body and toughened ground glass is used outdoor square whether to achieve...

About Phosphorescent Evacuation

On March 8, 2000, a subway accident took place in Tokyo. Trains derailed, six people were killed and sixty injured. If this accident had taken place in a tunnel instead of an open area, these numbers would certainly have been much higher. It is easy to imagine the panic caused if the accident victims were unable to determine the correct direction to evacuate the scene. In such situations, it would be very helpful if Glow-in-the-dark signs were installed in...

Specific operation method to improve the smoothness of powder coating

Powder coatings are one of the most environmentally friendly coatings systems due to their complete absence of organic solvents and low VOC emissions during curing. The so-called coating leveling, that is, coating coating after the construction of the formation of smooth state, leveling surface should not exist orange peel, brush marks, ripples, shrinkage cavity and other irregular form. Generally we use the naked eye direct observation method is to sample and standard samples for parallel comparison to judge the advantages...

Market application and development space of long afterglow self-luminous materials

In the field of building decoration, self-luminous materials are energy-saving, environment-friendly and low-carbon new building materials. The application of new self-luminous materials brings inestimable market value and practical value. City square, parking lot, residential pedestrian road, commercial pedestrian street, hotel, home decoration, traffic road zebra crossing update, traffic line, pedestrian walkway, roadside stone beautification, city riverside night, green pedestrian path, tourist attractions, pond edge beautification, etc., will be put into use a large number of self-luminous materials. So luminous...

About long after glow phosphorescence material

Abstract: The paper introduces the long after glow phosphorescence material Key words: long after glow, ZnS. Introduction How to define a luminescent substance it? Suitable materials absorb radiation energy , and then the light is emitted , the emitted photon energy is lower than energy of the excitation radiation. This behavior has a light-emitting substance called luminescent substances. According to the excitation can be divided into different photoluminescent material , a cathode ray emitting material , an electroluminescent material , a chemiluminescent...
