Change Color Deposition Film Thin film

Click For Summary

The color of thin films, particularly those made from carbazole molecular glasses, is significantly influenced by light interference. This phenomenon occurs due to varying film thickness and refractive index, leading to different wavelengths of light being amplified or diminished. The discussion highlights how these optical properties can be manipulated for applications in electronics and optics. Understanding the principles of thin film interference is crucial for optimizing material performance. Overall, the interplay between molecular structure and light interference plays a vital role in the color characteristics of these films.

Homework Statement: Hi everyone,I hope you are doing well.
I am trying to get a thin film of molecular glasses based carbazole , and during the deposition with physical vapor deposition I notice that the color change from brum to black liquid then we get a yellow thin film .
Please could you help me the understand what's happen ?
Thank you in advance for your interest.

Thread 'Product of two boosts and then two inverse boosts is rotation matrix'

So is there some elegant way to do this or am I just supposed to follow my nose and sub the Taylor expansions for terms in the two boost matrices under the assumption ##v,w\ll 1##, then do three ugly matrix multiplications and get some horrifying kludge for ##R## and show that the product of ##R## and its transpose is the identity matrix with det(R)=1? Without loss of generality I made ##\mathbf{v}## point along the x-axis and since ##\mathbf{v}\cdot\mathbf{w} = 0## I set ##w_1 = 0## to...
