LUMINESCENT POLYCARBONATE FILM FOR WHITE LIGHT-EMITTING DIODES AND DETECTORS Russian patent published in 2013 - IPC H01L33/50 G01T1/20 

FIELD: physics.

SUBSTANCE: disclosed is a flexible (self supporting) polycarbonate film filled with inorganic phosphors made from solid solutions of aluminates and silicates of rare-earth elements. The film is formed by moulding from a solution of a suspension of a polycarbonate and phosphor in chlorinated aliphatic solvents and contains 10-14 wt % polycarbonate, 4-8 wt % inorganic phosphor with a garnet structure, 0.08-0.8% plasticiser based on an acrylonitrile-styrene composition, 0.5-2% polyoxy monooleate surfactant and a solvent based on chlorinated aliphatic solvents selected from methylene chloride and/or chloroform, bringing its composition to 100%.

EFFECT: invention enables to form a polymeric luminescent flexible, self supporting polycarbonate film, which is suitable for use in scintillators, where contacting is carried out by mechanical attachment, as well as in semiconductor illumination structures in which there is adhesive attachment of a film, having optical contact with a heterostructure.
