TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Component: The substrate is chosen from glass, quartz, crystalline silicon wafers, and gallium nitride light-emitting diode with emission at 400 nm or 450 nm.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The doping is preferably performed using fluorescent organic pigments and nanoparticles of europium-doped aluminum oxide for obtaining polystyrene, and terbium, europium, cerium, and/or deuterium rare-earths with terbium-doped aluminum oxide nanoparticles for obtaining polyethylene terephthalate. Formation of luminescent polymer film further involves coating violet chips using the precursor solution containing mixture of blue, yellow and red fluorescent organic pigments at a ratio of 4:1:1, and coating blue chips using a mixture of yellow and red fluorescent organic pigments at ratio of 1:1. Preferred Component: The cesium ions and dysprosium ions are used as dopants for obtaining films having a white light emission. Preferred Properties: The luminescent film has an average transparency of 80%, roughness of 100-2500 Angstrom , and average thickness of 3 mu m. The film doped with fluorescent organic pigments shows major emission bands at 440 nm for blue, 507 nm for yellow and 590 nm for red. The film doped with three fluorescent organic pigments exhibits a luminescent emission of white light. The spectra of films doped with terbium show 4 defined peaks mainly centered at 490 nm, 547.5 nm, 590 nm and 622.5 nm and the emission is mainly concentrated on the peak centered at 547.5 nm associated with the transition 5D4 to 7F5, such that the dominant light emission is high intensity green color. The spectra of films doped with europium show 4 defined peaks centered at 590 nm, 612.5 nm, 650 nm and 697.5 nm and the emission is mainly concentrated on the peak centered at 612.5 nm associated with the transition 5D0 to 7F2, such that the light emission is high intensity red color. The spectra of the films doped with dysprosium show 3 peaks centered at 483 nm, 573 nm, and 663 nm, and the emission is mainly concentrated on the peak centered at 573 nm associated with the transition 4F9/2 to 6H13/2, such that the dominant light emission is yellow color. The films doped with cerium show peaks at 390 and 450 nm with a dominant peak associated with the transition 5d to 4f, such that the light emitted is bluish and intense.
