• ITMO Researchers Use Hybrid Crystal to Enable Simultaneous Grayscale and Color Direct Laser Writing

  With the new material suggested by ITMO physicists, it will be possible to embed grayscale images into color ones during direct laser writing. The researchers were the first to use metal-organic frameworks for the purpose; these are optically transparent materials that can transform laser radiation. When subjected to it, the material’s structure changes, with color defects formed inside. Each such defect has a unique scattering spectrum, making metal-organic frameworks useful in producing uncloneable anti-counterfeit trademarks. The material is described in a paper published in Advanced Functional Materials.

• ITMO Solution Prevents Counterfeiting of Glass Products

  Researchers from ITMO University have suggested a method of creating colored patterns with an affordable, domestically-produced laser. Compared to others, the new method makes it possible to create smaller separate patterns within a single bigger one, which are harder to forge. The technology, described in an article published in Optics and Laser Technology, will help prevent production of counterfeit glass products, such as medical vials and test tubes.

• ITMO Researchers Find Way to Make Packaging Cheap, Easy to Apply

  Color laser marking is a technology that helps brands protect their products by applying unique QR codes and barcodes. While the method is good at fighting counterfeiting, the process itself is rather complicated and time-consuming. But with the technology suggested by scientists from ITMO University, manufacturers can produce protective labels for a range of products, including jewelry and optical devices, in just two seconds with no expensive equipment needed. The results of the study were published in Materials Letters.

• New Lasers for the Modern Industry

  Promising laser technologies are used in medicine, navigation, industry as well as for falsification protection and art objects' preservation. ITMO University as one of the leaders in this field has received 31 million rubles for development of the unique laser systems. Currently, the University takes part in the Federal Target Program "Research and Development Projects in Top-Priority Fields Related to Science and Technology in Russia 2014−2020."
