Application areas:

Based on the concept of material genetic engineering, multi-channel wide-spectrum parallel high-throughput spectral testing technology and equipment have been developed, which can realize rapid spectral testing of luminescent materials, including phosphors, fluorescent films, fluorescent sheet samples, etc., which is especially suitable for arranging samples in an array form. Parallel testing to compare the spectral characteristics of each sample and obtain preferred results.

Technical characteristics:

Functional modular design, including: 1) a series of excitation light sources, which can be arranged as one or several light sources as needed to achieve multi-channel testing;2) a series of band-pass filters to achieve wide-spectrum testing;3) one corresponding to the light sources One or several optical fiber spectrometers are used to receive the emission spectrum of the material;4) an array sample table, where the samples to be tested are arranged in an array on the sample table for testing; 5) The sample stage moving stage moves in X-Y two-dimensional. Under the condition of incidence of excitation light, the sample stage is moved according to a fixed distance to realize the traversal test of the spectra of each sample on the sample stage;5) Spectral data processing and process operation control unit.

Performance indicators:

On-demand configuration: 1) Select LD or LED series light sources, and the excitation wavelength range is 365-980 nm;2) Configure a series of filters, and the spectral test range is 300-980 nm, and the resolution is 1 nm;3) The moving range of the two-dimensional sample moving stage can be designed on demand;4) The test time for a single sample is 0.5 minutes; the test time for a {6'9} array sample is 30 minutes;5) The test output results are the sample emission spectrum and color coordinates.

Current status:

Equipment prototypes were displayed in Changning Park and accepted entrusted testing services. I have applied for 1 China invention patent and are applying for 2 group standards.
