Method of modification of inorganic fluoride nanocrystals doped with rare earths iones

摘要

the subject of the invention is the modification of inorganic nanokrysztau0142u00f3w fluoride doped rare-earth ions with the nanokrysztau0142y of general formula naaf4: b3 + c3 +, in which a is yttrium (y) or jon rare earths selected from gadolinium (gd), europu (eu) or erbu (er), and b and c means lantanowiec selected from gadolinium (gd), europu (eu), erbu (er)tulu (tm), iterbu (lp), neodymium (nd) or terbu (tb), which on its surface contain trioctylphosphine oxide or oleic acid is dissolved in toluene or chloroform, the following acid meso - 2,3 - dimerkaptobursztynowy (dmsa) or 3-mercaptopropionic acid (3mpa) previously dissolved in di metylosylfotlenku (dmso) nagazowanym argon.then the mixture is subjected to the action of ultrasonic in the time from 1 to 5 hours or mixed using a magnetic stirrer in time from 1 to 5 hours, and then added methanol or ethanol and a whole odwirowuje, after which arose the nanokrysztau0142u00f3w dissolves in distilled water.
