ФЛУОРЕСЦЕНЦИЯ - выделение излучения, обычно света, из вещества, атомы которого получили избыточное количество энергии при бомбардировке частицами, как правило, ультрафиолетового излучения электронов. В отличие от ФОСФОРЕСЦЕНЦИИ, флуоресценция прекращается при отсутствии источника энергии. Пары ртути являются флуоресцентным веществом и используются для изготовления люминесцентных ламп для освещения автострад. Экран телевизора также покрыт слоем флуоресцентного вещества. На видео - флуоресценция флуоресцеин
