The array of microsamples is positioned on a computer-controlled XY translation microstage with a spatial resolution of 1\u03bcm so that the spectra can be mapped with micron precision. Micro-Raman spectrometers have a high spectral resolution of about 2cm\u22121 over the wave number range of 150\u20133900cm\u22121, while UV-vis and fluorescence spectrometers have high spectral resolutions of 0.4 and 0.1nm over the wavelength range of 190\u2013900nm, respectively. In particular, the signal-to-noise ratio of the micro-Raman spectroscopy has been improved by using a holographic Raman grating and a liquid-nitrogen-cooled charge-coupled device detector. The performance of the combined spectroscopy system has been demonstrated by the high-throughput screening of a combinatorial ferroelectric (i.e., BaTixZr1\u2212xO3) library. This system makes possible the structure analysis of various materials including ferroelectrics, catalysts, phosphors, polymers, alloys, and so on for the development of novel materials and the ultrasensitive detection of trace amounts of pharmaceuticals and diagnostic agents.<\/jats:p>","DOI":"10.1063\/1.2755745","type":"journal-article","created":{"date-parts":[[2007,7,12]],"date-time":"2007-07-12T14:12:22Z","timestamp":1184249542000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Combined micro-Raman\/UV-visible\/fluorescence spectrometer for high-throughput analysis of microsamples"],"prefix":"10.1063","volume":"78","author":[{"given":"Jermim","family":"Noh","sequence":"first","affiliation":[{"name":"Korea Advanced Institute of Science and Technology Department of Chemical and Biomolecular Engineering (BK21 Graduate Program), , 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea and Center for Ultramicrochemical Process Systems, , 373-1 Guseong-dong, Yuseong-gu, Daejeon, 305-701, Korea"},{"name":"Korea Advanced Institute of Science and Technology Department of Chemical and Biomolecular Engineering (BK21 Graduate Program), , 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea and Center for Ultramicrochemical Process Systems, , 373-1 Guseong-dong, Yuseong-gu, Daejeon, 305-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yung Doug","family":"Suh","sequence":"additional","affiliation":[{"name":"Korea Research Institute of Chemical Technology Advanced Materials Division, , P.O.
