TOMSK, Aug 15 – RIA Tomsk, Yana Kuzminykh. Scientists of Tomsk Polytechnic University (TPU) are engaged in the
technology manufacturing of luminescent ceramics, which due to its low cost in
the future will be able to replace the LEDs, the press service of the
university said on Tuesday.
According to the
press service, TPU scientists receive products from luminescent, transparent
and nanoceramics on a spark-plasma sintering plant for powder materials.
Ceramic powder is placed in a special shape and, heated by an impulse current,
is compressed. Depending on the composition it is possible to get different
spectra of ceramics luminescence.
"The
technology of luminescent ceramics receiving, which can become a cheaper
alternative to modern light sources, is developed by scientists of Tomsk
Polytechnic University. Transparent ceramics can replace LEDs in the future,
its use will significantly reduce the cost of production of automobile
headlights and other light sources", – is said in the report.

It is specified
that one more advantage of luminescent ceramics is its higher strength.
Ceramics is used in a variety of areas: electronic, defense, oil and gas,
automotive and others, as well as in the fields of electricity and medicine.
It is added that
for the development of technologies for the production of transparent and
luminescent ceramics, the scientific team of the Department of Nanomaterials
and Nanotechnologies of TPU received grants from the Russian Science Foundation
and the Russian Foundation for Basic Research. International research work is
carried out with the University of Chongqing (China).
