The photoresponse and photoconductivity properties of micron-sized C60whiskers and sub-millimeter-sized C60clusters are successfully studied by the microfabrication technologies. According to the ultraviolet-visible-near infrared (UV
Laser crystals of LiYF4(LYF) singly doped with Er3 in 2.0% and co-doped with Er3 /Yb3 in about 2.0%/1.0% molar fraction in the raw composition are grown by a vertical Bridgman method. X-ray diffraction (XRD), ab
