Electrodeposition of luminescent composite metal coatings containing rare-earth phosphor particles

摘要: Mixtures of acetamide and dimethylsulfone (DMSO2) with dissolved anhydrous transition metal chlorides are introduced as new non-aqueous electrolytes for the preparation composite coatings embedded hydrophilic particles via an electrolytic co-deposition process. Red-emitting (Eu2O3 Y2O3:Eu3+), yellow-emitting (Y3Al5O12:Ce3+), green-emitting (Gd2O2S:Tb3+) blue-emitting (BaMg2Al16O27:Eu2+) rare-earth phosphor yttrium oxide have been into thin nickel cobalt layers. The a metallic lustre, but show at same time photoluminescence upon irradiation UV light. spectroscopic photophysical properties phosphors not modified by embedding them in host matrix. Different electrodeposition parameters were optimised order to obtain well-adherent uniform particle distribution. By preparing mixtures Y2O3:Eu3+ Gd2O2S:Tb3+ phosphors, emission colour could be varied from red orange yellow green, depending on mixing ratios. Embedding blue layer made it possible produce white photoemission.
