Method and system for predicting emission wavelength of phosphorescent material

The invention provides a light-emitting wavelength prediction method and system of a phosphorescent material, and belongs to the technical field of performance prediction of a light-emitting material, and the method comprises the following steps: obtaining molecular characteristics of a to-be-detected phosphorescent material; processing the obtained molecular characteristics of the to-be-detected phosphorescent material by using a pre-trained wavelength prediction model to obtain the light-emitting wavelength of the to-be-detected phosphorescent material; wherein the pre-trained wavelength prediction model is obtained through training of a training set, and the training set comprises molecular characteristics of a plurality of phosphorescent materials and labels for labeling light-emitting wavelengths corresponding to different molecular characteristics. According to the method, related features of a phosphorescent material in a data set are extracted, key features are screened as input, light-emitting wavele
