Increasing in the polar angle of sample yield to shifted absorbed wavelengths to the smaller wavelengths. Also, with the increase of azimuthal angle, the absorbed wavelengths will shift to the larger wavelengths which are very suitable in sensor applications. %> http://opsi.ir/article-1-491-en.pdf %P 1109-1112 %& 1109 %! %9 Research %L A-10-1-471 %+ %G eng %@ 1126-3278 %[ 2015
