Near Infrared Emission

The visible and near infrared emission spectra of Er3+/Tm3+-doped Ga2O3-Bi2O3-PbO-GeO2(GBPG) glasses excited at 808 nm are experimentally investigated. The results reveal that 1.53 µm emission were enhanced with an increase of Er3+concentration. Furthermore, the incorporation of Er3+into Tm3+-doped systems has also resulted in intense 522, 545 and 693nm upconversion emission intensity and an weak 660 nm red emission. The possible mechanism and related discussions on this phenomenon have been presented. The results show that Er3+/Tm3+-codoped GBPG glass may be a promising materials for developing laser and fiber optical devices.

Systematic Lymphadenectomy

The role of pelvic sentinel lymph node dissection (SLND) is increasing in oncological pelvic surgery, especially in the management of cervical and endometrial cancer.SLND using indocyanine green (ICG) is safe and effective, and its sensitivity is higher than with other detection methods. The advantages of ICG are its low toxicity, its confinement within the vascular compartment, its rapid excretion, and the rarity of allergic reaction. These advantages confer to this fluorescent dye a superiority over blue, which can cause anaphylactic reactions. Using ICG does not require advance planning involving nuclear protection and delayed surgery, as are mandatory when using 99Tc detection. ICG allows the surgeon to visualize the lymph nodes through the peritoneum and thus avoid wide dissection.According to European guidelines,1 the indications for SLND in cervical cancer are for patients with FIGO (International Federation of Gynecology and Obstetrics) IA1–IA2 disease, lymphovascular space involvement - positive status, without systematic pelvic lymphadenectomy – and patients with FIGO IB1–IIA1 disease, prior to systematic pelvic lymphadenectomy. Guidelines1 2 for endometrial cancer management state that SLND is indicated in cases of low-risk endometrial cancer (FIGO IA, grade 1–2), without systematic lymphadenectomy in cases of non-detection, with the technique being preferable to systematic lymphadenectomy in cases of intermediate-risk endometrial cancer (FIGO IB, grade 1–2, or FIGO IA, grade 3).2 Our objective is to review the technique of ICG injection and the real-time detection of pelvic SLNs using near-infrared imaging by means of a step-by-step explanation of the procedure using an instructional Video 1.

Near Infrared Emission

In this article, we report on enhanced broadband near-infrared emission in Yb–Bi codoped phosphate glasses. The emission intensity of Yb–Bi codoped glass was ˜32 times larger than that of Bi-doped glass when excited with 980-nm laser diode. The highest 1/e fluorescent lifetime of Yb–Bi codoped glass reached 1650 μs. The dependence of emission intensity and fluorescent lifetime on Yb2O3 concentration was investigated. The enhancement of the near-infrared emission is due to energy transfer from Yb3+ (2F5/2–2F7/2) transition to Bi ions, and the highest energy transfer efficiency reached 50%. Yb–Bi codoped phosphate glass should be a promising candidate for broadband optical amplification.
