Photoluminescence and Optical Transition Dynamics of Er^(3+) Ions in Porous Si

Journal of Materials Science & Technology 1999年第4期15卷 357-362页

Er was doped into porous Si by immersing the porous Si sample in a saturated ErCl3,ethanol solution. Sharp and intense 1.54 μm photoluminescence caused by intra-4f-shefl transitions in Er3+ ions was observed up to room temperature. It is shown that the immersing process is valid to dope Er in high concentration in porous Si. Time resolved study of the Er-doped porous Si revealed that the doped Er3+ ions are excited by energy transfer from photo-generated electron-hole pairs in the host. The energy back transfer process from the excited 4f electrons in the Er3+ion to the host is not a dominant factor to quench the Er-related emission in porous Si. Ourresults are well explained by a proposed model in which an intermediate state was introduced.

Successful photodynamic therapy for biliary papillomatosis:A case report

Papillomatosis of the bile duct is a rare disease with a high risk of malignant transformation. Therapeutical options include partial hepatectomy and liver trans- plantation. A previously healthy 65-years old male developed jaundice and right upper abdominal quadrant pain in 1996. A villous adenoma of the distal bile duct was diagnosed. A Whipple procedure was performed. In 2002 the patient turned symptomatic again. An- other adenoma was found in the right hepatic duct resulting in a right hepatectomy. Two years later the patient again developed cholestasis. Alter drainage of the left hepatic duct with a percutaneous transhepatic cholangial drainage （PTCD） catheter, a recurrent biliary adenomatosis was diagnosed by cholangioscopy. As there was no surgical option left, the patient received photodynamic therapy （PDT） for the recurrent biliary papillomatosis. Three mo alter he received further photodynamic therapies, the bile duct epithelium appeared normal and the patient had no signs of adenomatosis, both macroscopically and histologically. The follow-up cholangioscopy in late 2005 revealed only a small papil-loma without the need for intervention. In early 2006, the patient died of multi organ failure without signs of extrahepatic cholestasis or cholangitis at the age of 75, 10 years after the diagnosis of biliary papillomatosis was established. The patient exceeded the average life expectancy of patients with biliary papillomatosis by far. Thus, PDT might be a sufficient therapeutic option for recurrent papillomatosis patients with no significant side effects.
