Jen-Fan Peng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymorph, polymorph screening system, and polymorph preparing and screening method
    Patent number: 8865093
    Abstract: A polymorph, a polymorph screening system, and a polymorph preparing and screening method are disclosed. The polymorph preparing and screening method includes the following steps: providing a plurality of substrates of different materials; causing an organic material to grow crystals on the plurality of substrates through solution-cooling crystallization process, so that a plurality of polymorphs with different characteristics are prepared; and screening the plurality of polymorphs prepared in the previous step to obtain polymorphs with desired characteristics.
    Type: Grant
    Filed: October 20, 2011
    Date of Patent: October 21, 2014
    Assignee: National Central University
    Inventors: Tu Lee, Shih-Chia Chang, Jen-Fan Peng, Pu-Yun Wang, Yu-Kun Lin
  • Optical device having solvate and manufacturing method thereof
    Patent number: 8263970
    Abstract: The present invention discloses a manufacturing method for an optical device having a solvate, comprising the following steps: providing a substrate, depositing a solute on the substrate, and placing the substrate in the vapor environment of a solvent such that the solvent and the solute on the substrate form a solvate exhibiting optical properties. Furthermore, the present invention provides an optical device having a solvate, which modulates the photoluminescence (PL) intensity of the optical device via the solvate. The optical device is obtained by means of the above-described manufacturing method.
