Embodiment Construction

[0019] The composition of the present invention is as figure 1 shown. It includes a temperature control device 1, a sample stage 2, an ultraviolet light source 6, a lens 7, a spectrometer 8, a computer 9, and an optical bench 10. The temperature control device 1 is connected to the sample stage 2 and the ultraviolet light source 6. The temperature control device 1 can be a sample stage 2. Provide precise temperature. The sample stage 2 is covered with heat insulating material 3 for heat preservation. For heat preservation and light transmission, a thin quartz plate 4 is set on the surface of the sample material 5, and the lens 7 is placed between the sample stage 1 and the spectrometer 8 , the sample stage 1 and the lens 7 are placed on the optical bench 10, the optical bench 10 is placed on the slide rail 11, the lens 7 converges the fluorescence excited by ultraviolet light into parallel light and aligns it with the slit of the spectrometer 8, and the ultraviolet light sourc...

Abstract

A device for measuring temperature transition character of fluorescent material is featured as connecting temperature control device to sample table, setting lens in between the sample table and spectrometer, setting sample table and lens on optical bench set at top of sliding track, focusing fluorescent triggered by ultraviolet light to be parallel light being aligned to gap of spectrometer and setting ultraviolet light in front at one side of sample table.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device and method for the temperature characteristic of fluorescent materials. Background technique [0002] Fluorescent material is a material widely used in construction, road, decoration, chemistry, biology, medicine and other fields. Fluorescent materials are very sensitive to temperature. At different temperatures, the fluorescence intensity and wavelength of the material will change. The temperature characteristic of fluorescent materials is an important optical performance index. Its characteristic not only affects the application range of the material, but also the temperature effect of material fluorescence is the basis of modern fluorescent temperature sensors. It is of great significance to study the fluorescence-temperature behavior of materials. The general-purpose grating spectrometers generally sold on the market can generally achieve a r...
