  Like indium tin oxide, ZnO thin film is a transparent conducting oxide. Some advantages over ITO include: low material cost, non-toxicity high chemical stability under hydrogen plasma Applications LEDs solar cells liquid crystal displays Doping agents for ZnO Al-doped (AZO) Ga-doped ZnO (GZO) F-doped AnO (FZO)  atomic radius (0.136 nm) is similar to that… Continue reading F doped ZnO

Complexes of Mg, Sr, Ba, adn Al have been used to dope aluminum fluoride glasses as a way to improve optical properties.  (Ozuturk (1998)  One draw back to these glasses is the tendency of crystal formation and phase separation due to florine evaporation and acid corrosion of the  crucible upon casting. Slow cooling is desired to… Continue reading Barium Metaphosphate

Two recent material science examples of aluminum metaphosphate is as a host for transition metal phosphors in scintillation detectors.   Aluminum metaphosphate glass to detect ionizing X-ray radiation Kei Kagami and coworkers (2018) developed a scintillation glass to detect ionizing X-ray radiation such as might be found in a medical setting. While single crystals have… Continue reading Aluminum metaphosphate

A light emitting diode (LED) is any substance that emits light when a current passes through it  through it. Blue LEDs were quickly followed by yellow LEDs.  While LEDs can be obtained by combining blue and yellow LEDs using the complement color system.   Unfortunately,  glitches in color rendering result in the "white LED" light appearing… Continue reading Dy2O3 and white LEDs

Traditional rare earth iron boron permanent magnets have the disadvantage of Low coercivity, i.e. they tend to become demagnetized  in an externally applied magnetic field. Li and coworkers arc melted an industrial rare earth (RE) alloy with abundant La and Ce (RE100 = La30.6Ce50.2Pr6.4Nd12.8, ) with iron (99.9 wt.%), and iron-boron alloy (99.5 wt.%).  The nominal  composition of the… Continue reading Dy2O3, making permanent magnets more permanent
