Definitions

  • This invention relates to a glass container that glows when placed in a dark environment or under black light after being exposed to a source of visible light for a certain duration and a method of production of the same.
  • the ground energy level or the ground state of an atom or a molecule is attained when the electrons of an atom or a molecule occupy orbitals with the lowest energy.
  • An electron configuration wherein electrons occupy higher energy levels is defined as an excited state of an atom or a molecule.
  • some materials Upon exposure to a light source, some materials transition into an excited state by absorbing the radiation impinging on them. When radiation ceases, they emit photons having an energy equal to the energy gap while relaxing to the ground state from an excited state.
  • Visible photoluminescence falls under two categories as fluorescence and phosphorescence according to the duration of the event. (Time required for the electron to return to the ground state energy level).
  • a singlet or a triplet state is formed.
  • the spin of the excited electron is still paired with the electron in the ground state.
  • the triplet state spins of the two electrons are in an unpaired configuration and the features of a molecule in an excited triplet state significantly differ from one in an excited singlet state.
  • Light emitted by the transition from an excited triplet state to the ground singlet state is called phosphorescence.
  • a triplet— » singlet transition is more likely than a singlet— » singlet transition; therefore, the average life span of an excited triplet state is longer than the life span of a singlet state and therefore an emission resulting from this transition may last a little longer after radiation ceases.
  • Fluorescent radiation always occurs at a longer wavelength than the absorbed radiation, that is, it has a lower energy.
  • Phosphorescence can be defined as a type of glow related to fluorescence. Unlike fluorescence, phosphorescent materials do not reemit the absorbed energy quickly. Moreover, it is unlikely that a molecule in the ground state is excited to a triplet state and the intensity of the absorption peaks resulting from this process is a few orders of magnitude lower than the similar counterparts of a singlet-singlet transition.
  • Phosphorescent materials find use in many fields, primarily in plastics and paints. Chemical materials with phosphorescence are supplied as pigments and they endow the surface on which they are applied with a glow in the dark property. Glass is more challenging with regards to the applicability of paints compared to many other surfaces like metal, wood, paper, composite, plastic and concrete. When existing phosphorescent paint systems are applied to a glass surface, mechanical strength and glow efficiency are found to be poor. It is possible to give glowing property to a glass by adding pigments with phosphorescent effect to the glass composition. However, in this method, phosphorescent pigments cannot be distributed homogeneously in the glass composition. In addition, this method is rather costly.
  • Phosphorescent paints that are available in the market may be applied on different surfaces, whereas, sufficient and efficient adhesion cannot be attained on glass surfaces.
  • phosphorescent pigments When phosphorescent pigments are incorporated in non-pigmented (colorless) paint systems compatible with glass surfaces, decadence (phase separation) problems are experienced.
