Commercialization of tip-enhanced Raman scattering microscope
The project succeeded in product development of tip-enhanced Raman scattering microscope that utilizes light intensity enhancement by plasmon resonance. The product is now to be sold from a startup company. The technology has been under basic research for 20 years. The manufacturing technique of sharp nano-structured metal probes is the key technology.
Development of wavelength conversion crystals for UV light sources (CLBO)
- The nonlinear optical crystal, CsLiB6O10（CLBO）generates 266 nm UV light with high efficiency and is used for UV lasers.
- The crystal is synthesized at first at Osaka University and crystal defects are reduced ultimately at the Photonics Center to realize a high power solid-state laser as high as 3W.
- This wavelength conversion crystal has been and will be used for semiconductor mask inspection and next generation fine laser fabrication systems.
Using high-quality CLBO crystal growth technology, the project successfully extended the lifetime of crystal devices. At present, preparations are being made to set up a venture business within the Photonics Center to start producing what is being called Osaka-CLBO by the end of fiscal 2013 2014 . Through partnerships with manufacturers of lasers and laser beam machines, the project aims to develop UV lasers and UV laser beam machines using CLBO crystals.
Productization of gas chromatograph systems
Released in February, 2013
- The high-sensitivity gas chromatograph system(GC) , Tracera, employs a barrier discharge ionization detector (BID) based on a new plasma technology; atmospheric pressure He plasma.
- This GC system enables trace analysis at a sensitivity of 0.1ppm level more than 100 times that of the conventional thermal conductivity detector (TCD) and over twice that of the flame ionization detector (FID).
- It has been nearly a half-century since gas chromatograph systems have seen the emergence of a universal detector based on novel principles.
- This system is the product of a new collaboration between academia and industry; Osaka University and Shimadzu Corporation.
Together with Shimadzu Corporation, one of the member companies, this project pursued applied research on plasma photonics to develop the Tracera gas chromatograph, which features significantly enhanced sensitivity and is now marketed throughout the world by Shimadzu Corporation. The system is capable of handling more samples than conventional detection methods with high sensitivity .
Development of eco lamps
Established in June, 2014
- High efficiency comparable to LED due to radiation control with metal material structure.
- It does not generate heat because infrared radiation is suppressed.
- Microcavity engraved on the filament enhances light emission efficiency.
- Full-spectral light without using a filter natural and friendly to human.
- Prototyping is enabled by “Cannery for photonics products” at the Photonics Center, Osaka Univ.
This project succeeded in developing electric incandescent lamps that can regulate thermal radiation spectra. They demonstrated that spectra would change depending on the size of tiny holes made on the surface of the incandescent lamp filaments . The our goal is to realize more efficient full-spectrum light sources.
Worldwide Best Quality GaN Crystal
- High-quality GaN crystals similar to that of Si is grown by unique crystallization techniques; the Na-flux method using seed crystals.
- The growth by Na-flux method brings out a high quality GaN crystal of a dislocation density about 105 /cm2 from a starting seed crystal with dislocation density of about 109 /cm2 prepared by Dr. Amano’s method employing low-temperature deposited buffer layers.
- High-quality GaN crystals are indispensable for next generation devices such as ultra-high -definition display, low-loss power devices and high speed transistors.
