چکیده انگلیسی
The UV-visible spectroscopy of laser irradiated lithium colloids and ionic liquids has been investigated. TEM00 mode 1064Â nm DPSS laser (LSR1064NL) of intensity 148Â W/cm2 and 950Â mW power was passed through Li containing Acetonitrile, Methanol, Hexane, 1,4-Dioxane and Chloroform for 30Â min. The Li metal and laser irradiation markedly affected the lower wavelength cut-off i.e., pattern of absorption spectrum of solvents and colloids. The sharp band at 190Â nm and two new broad bands at 256Â nm and 292 nm are presumably due to the formation of monolithium derivatives of Acetonitrile (i.e., Li-CH2CN, Li-CHCNH, Li-CCNH2, CHCN-Li-H and CH2Â âN-Li) on irradiation. However comprehensive research on same is required to be performed. The present study is certainly helpful in understanding the long-term performance and the mechanism by which the properties of colloids change.
