DEVICE FOR FLUORESCENT MATERIALS' DECAY TIME TEMPERATURE-DEFENDENCE DETERMINATION

摘要

The device consists of a rotating disc (2) for application of a sample (1) of luminophore. The rotation disc (2) arranged on the first axle (3) is in a solid cover (16) made of heat-conducting material and is equipped with a heating element (17) and a thermometer (20). Opposite the rotation disc (2) opposite its rotation centre on the second axle (12) there is a rotating guide (11) with the length identical with the semi-diameter of the rotation disc (2), and on the guide (11) there is a shiftable sensor (10) sensitive to light. Behind the rotation guide (11) parallelly with the rotation disc (2) there is a plate (8) with a fissure (7) equipped with a screen (9) for regulation of the fissure (7) width. The fissure (7) to the height equal to the semi-diameter of the rotation disc (2) and its lower edge are positioned in the level of the rotation centre of the rotation disc (2). In front of the plate (8) opposite the fissure (7) there is an excitation source (6).<IMAGE>
