Japan to develop non-mercury light source in the medical field have excellent results

篠 Tin plasma and Kobe University, Hyogo Prefectural industrial technology center and Japan YUMEX common developed using 篠 Tin plasma development monitor "PTA (Plasma Tube Array)" film-ultraviolet (UV) surface light source.

The target is actually applied to UV treatment, medical and industrial purposes.

The development of surface light source for medical purposes with the excellent treatment results, may issue 311nm wavelength ultraviolet rays.

Luminous wavelength bandwidth only $ 1.5nm, luminous intensity about 2mW/cm2, ideal for use in the medical field.

Medical use of UV light source mostly use mercury (Hg) lamp light, from the perspective of environmental load, you need to use mercury-free alternative light sources, this surface light source is non-mercury light source.

Development in general there are two main points.

First, the display of structural improvement to PTA suitable for lighting devices. Second, the development of a specific wavelength to gather energy and UV luminescence of phosphor. Phosphor with rare earth elements gadolinium (Gd).

Trial production of surface light source size, thickness 0.7mm 30cm×30cm.

Weight approximately 100g.

This is as Japan's economy and industry 2009-2010 annual research and development of the "regional innovation, business," by 篠 Tin plasma and three other research groups are made up of the research and development.

Details about the development of technology, in 2010 14 September starting at Nagasaki University seminar "held in fall 2010, paragraph 71-applied physics academic lecture sessions had announced.
