David Sarnoff Research Center |
The David Sarnoff Research Center is
participating in the Phosphor Technology Center of Excellence (PTCOE) through
the execution of three technical programs and one educational program. The
technical programs involve the synthesis of phosphor materials. One program
deals with the preparation of phosphors for thin film electroluminescent
(TFEL) displays and involves basic materials preparations, followed by the
fabrication of the materials into sputtering targets, which are then sent
to members fabricating the displays. Another program is concerned with the
development of powder phosphors for field emission displays. In this program,
powder phosphors are prepared as part of the search for new and/or improved
phosphors that show optimum properties for current saturation, maintenance
characteristics and chromaticity. The remaining technical program involves
the development of new or improved phosphors for plasma display panels (PDPs).
Again, powder phosphors are synthesized in search of materials that have high
vacuum efficiency for excitation in the vacuum ultraviolet region of the
spectrum, good maintenance and acceptable chromaticity.
The educational program consists of presenting seminars at the member
universities on phosphor technologies and conferring with students carrying
out phosphor programs. Students occasionally visit the Sarnoff Research
Center to observe first hand the phosphor synthesis techniques. In addition,
talks are presented at various technical conferences on phosphor technologies
and properties.
Current Projects:
Education and Advisement of Technical Groups
P. Niel Yocom
Research Objectives:
- Help technical groups with commercial phosphor requirements and techniques
- Advise Universities on synthesis techniques
- Give Seminars to universities on phosphor technology
- Maintain contact and liaisons to other groups such as National Labs
(NCAICM)
