Photoluminescent materials with long afterglow was developed as a base of non-radioactive luminescent paints used for various signs and directions, means providing safe traffic, marking of roads, important devices and control elements, microcrack and microdefect revealing (paste), wall painting, in art and polygraphy, office and shop window decoration etc., as well as a filler for plastics, films, artificial fibres, leathers, rubbers, textiles, ceramics and various articles on their base (e.g. clothes, bijouterie, toys, souvenirs, switches, special means for equipment of police, rock-savers and fire-brigades and other purposes).
   Sources of excitation of emission (fluorescence) these of photoluminescent materials may be daylight, luminescent and incandescent lamps, UV-emitters. They convert UV- and visible light into various coloured luminescent emission with afterglow duration from minutes to several hours.
   The offered phosphors can work within the temperature range from -50C to +1000C and are stabile in different environmental conditions.
