Temperature Dependence of the Excimer Laser Coloration of KBr

Effect of processing environment on laser-induced darkening evolution in magnesium alloy

“…Laser-induced coloration of material surfaces provides many promising engineering applications including decorations, photocatalysts, product identification, and biocompatible implants, and it also offers an alternative approach to understanding of coloration theory [1][2][3][4][5][6][7][8][9]. Zhao et al [1] and He et al [6] ascribed laser-induced coloration of WO 3 to photoinduced thermochromism, which was different from ordinary photochromism induced by UV light.…”

Laser surface processing of ultralight magnesium alloys

“…Laser-induced coloration of material surfaces is an interesting phenomenon, and it provides an alternative approach to the understanding of coloration theory and also to many promising applications, such as decorations, product identification, biocompatible implants and photocatalysts (Malhotra et al 1991;Zhao et al 1997;Bichevin et al 1998;Anpo and Takeuchi 2003;Takemoto et al 2004;Bartlett 2006;He et al 2008;Zheng et al 2002;Li et al 2009;.…”
