Abstract

The invention discloses a variable-temperature spectrum testing device. The variable-temperature spectrum testing device comprises an operating system, a temperature changing system, a measuring system, a cooling system and an analyzing system, wherein the operating system is used for setting a test temperature; the test temperature is transmitted to a temperature control device in the temperaturechanging system through a data transmission line; the temperature control device controls the temperature of a variable-temperature objective table according to the test temperature; and after the temperature of the variable-temperature objective table on which the test sample is placed is stable, an integrating sphere is closed for measurement, and a probe transmits received light emitted by thetest sample and a light signal generated by the excitation light source exciting the sample to the analysis system to obtain optical performance parameters of the test sample at different temperatures.

Description

technical field [0001] The invention belongs to the technical field of optical measurement, in particular to a variable temperature spectrum testing device. Background technique [0002] In recent years, with the vigorous development of semiconductor LED lighting, lighting and other fields, high-performance solid-state light-emitting materials have attracted extensive attention in high-end technology fields such as information technology, new materials and new energy. At present, from the perspective of basic research, the routine testing of solid-state luminescent materials can no longer meet the needs of researchers for material performance evaluation. For example, under the conditions of high temperature 150° or low temperature -30°, some special physical and chemical Phenomenon. On the other hand, in the field of engineering technology applications, the physical properties of luminescent materials are often affected by external operating conditions, so it is necessary t...
