DEVICE FOR synthesis Colloid semiconductor nanocrystals low-temperature sol-gel method

摘要

Utility model notnositsya to machinery for the synthesis of colloidal quantum dots by low-temperature sol-gel method and is used to obtain the experimental samples gelatin films colloidal quantum dots, the synthesis of which is realized by sol-gel method, providing a manifestation of the quantum size effects in the absorption and luminescence spectra. The technical effect of this is to provide for one synthesis cycle is up to 0.5 kg of a sol containing quantum dots ranging in size from 1 to 50 nm, and is achieved in that the device for the synthesis of colloidal semiconductor quantum dots low temperature sol-gel method comprising thermostatted reactor, a liquid thermostat, pump, agitator with motor and power supply of the motor, according to the utility model comprises a pH-meter, frequency counter, thermostated reactor capacitive type, and which is of a cylindrical vessel of stainless steel with double walls and fittings in the upper part for connecting the liquid of the thermostat; wherein the peristaltic pump is used, and the reactor cover has a window control and visual access ports for introducing reactants electrode pH-meter, stirrer, thermometer.
