Method for increasing the the intensity of the luminescence of quantum dots suspended

摘要

way of increasing intensity of luminescence of quantum dots of zirconium dioxide doped rare earth elements such as terbium, europium, praseodymium (zro2: re (re = tb, eu, pr)), and radiation in the visible light, is that during the pr manufacture of suspension ocesu dotsin which first in distilled water soluble compound containing zirconium ions or cyrkonylowe, and subsequently in the obtained solution dissolves the relationship terbu, europu or prazeodymu, changing ph value solution to the value of 7 - 12, the sediment shall be rinsed in distilled water and after ddaje process solwotermalnemu wspomaganemu mikrofalowo,the reaction mixture is placed in water, ethanol or their mixture and under a pressure of 2 - 20 mpa, held to 1000 hours, after which the product obtained shall not be washed, added to a solvent and subjected to ultrasonic impact, moving ions sc3 +, y3 +, la3 +, ca2 +, mg2 + in an amount not greater than 20% mol., advantageously in the form of soluble salts in water.
