  • Publication number: 20250223492
    Abstract: The present invention provides a bivalent platinum or palladium metal complex phosphorescent material based on dibenzothiophene coordination and the use thereof. Wherein the phosphorescent material has the general structure shown in Formula (I): The complexes of the present invention are based on novel tetradentate ligands of 4-phenyldibenzothiophene and pyridoxyl anions and derivatives thereof, which are coordinated with central metal ions to form 6/5/6 type tetradentate cyclometallated complex phosphorescent materials, and the presence of Pt—S coordination bonds makes such materials have significant temperature response characteristics. The luminescence intensity increases with the decrease of temperature, and the emission wavelength blue-shifted with the decrease of temperature. The blue-green luminescence was observed at 77 K, but the yellow luminescence was observed at 289 K, which indicated the potential application in optical thermometers.

  • Publication number: 20250218090
    Abstract: A cohort corresponding to a wearer of a head-mountable display (HMD) is selected from a number of candidate cohorts that each correspond to a different facial type. A set of facial images of the wearer is captured using one or multiple cameras of the HMD. A machine learning model for the selected cohort is applied to the captured set of facial images to predict blendshape weights for the facial expression of the wearer exhibited within the captured set of images. Each candidate cohort has a differently trained machine learning model. The predicted blendshape weights for the facial expression of the wearer are retargeted onto an avatar corresponding to the wearer to render the avatar with the facial expression, and the rendered avatar is displayed.
