The ALT Conference series are focused on the recent achievements and advances in laser technology and laser applications in various areas. These series of conferences, held annually since 1993, were established by Nobel Prize laureate Alexander Prokhorov, director of the General Physics Institute of the Russian Academy of Sciences. Previous conferences were organized in Russia, Czech Republic, Germany, Greece, France, Italy, Romania, Switzerland, United Kingdom, China, Hungary, Finland, Turkey and The Netherlands. The key topics of the conference are Biophotonics, Optoacoustics, Laser Diagnostics and Laser-Matter Interactions, Non-linear Optics Materials and Devices, Laser Systems and New Laser Materials, Terahertz Spectroscopy and Applications. Leading scientists and researchers from all over the world are invited to attend the Conference and make presentations reviewing the latest results in their field of interest. The activities of the 19th International Conference on Advanced Laser Technologies will take place in Golden Sands Resort on Bulgarian Black Sea Coast. Golden Sands (Zlatni Piasaci) is one of the biggest holiday resort complexes along the northern coastline, famous for its healing hot-water mineral springs as well as its beautiful two-mile (4 km) stretch of fine sandy beach, making it a popular holiday destination. The resort is located 11 miles (18 km) north of Varna, and sits at the foot of the forested hills of the Zlatni Piasaci National Park. Its ideal weather conditions with plenty of entertainment, sporting activities, warm and clean water, year round luxury hotels and villas, restaurants, bars and spa treatments, making Golden Sands one of the more desirable destinations on the Black Sea Coast. This part of Bulgaria is also reach of historical places, romantic towns and beautiful natural landscapes, and we hope that you are able to spend some extra leisure time to visit some of them. We do welcome you to this typical Bulgarian sea resort, with its well equipped conference center with extensive facilities. We hope that you will have a fruitful meeting, that you will make new friends and will meet old ones and will keep Bulgaria in your heart.

Box 790, SE-22007, Lund Sweden [email protected] Upconverting nanoparticles have recently drawn increasingly attention as a contrast agent for [1,2] optical bioimaging . Among upconverting nanomaterials, lanthanide-ions-doped NaYF4 nanoparticles have been shown to be the most efficient. A major advantage with upconverting contrast agents is that due to the anti-Stokes shift of the emission, autofluorescence, otherwise yielding a relatively intense superimposed background signal, can completely be filtered out. This is because autofluorescence will be emitted in a different wavelength region than that from the nanoparticles[3]. Other advantages are the wavelength regions for the excitation and emission will be within the tissue optical window[4], and that the spatial resolution will be improved as compared to fluorescence-based contrast agents[5-8]. [9-10] Currently, NaYF4 nanoparticles are synthesized in batch-control modes in small volumes . Although great achievements have been made, batch syntheses tend to suffer from irreproducibility, in terms of quality of the nanoparticles, from batch to batch and difficulty to implement fast screening.
