Understanding physical insights of making different lead halide perovskite nanocrystals remained in limelight of current research because of their strong emission tunable in entire visible spectrum. Optimizing reaction parameters, intensifying the emission, modulating A, B and X sites for bringing optical and phase stability, understanding the interface and ligand chemistry, investigating the growth kinetics, tuning the dimension, making heterostructures etc. were intensively studied. In addition, several aspects of colloidal nanocrystals such as the time dependent growth and obtaining size tunable nanocrystals as a function of time from one reaction, controlling anisotropic growth or stabilizing other than six facets of cubes, formation of various heterostructures with epitaxial growths etc. could not be established largely. Hence, while the field is emerging among efficient optical active materials, addressing these issues with summarizing different directions of research became timely important. Under these prospects, this perspective focused on top developments in the field of synthesis modulations where successes have been achieved and also summarized several directions of research where physical insights still could not understood broadly.

Stable cesium atoms that have the same atomic number as the element cesium, but differ in atomic weight. Cs-133 is a naturally occurring isotope.
Unstable isotopes of cesium that decay or disintegrate emitting radiation. Cs atoms with atomic weights of 123, 125-132, and 134-145 are radioactive cesium isotopes.
A member of the alkali metals. It has an atomic symbol Cs, atomic number 50, and atomic weight 132.91. Cesium has many industrial applications, including the construction of atomic clocks based on its atomic vibrational frequency.
Injury to the nervous system secondary to exposure to lead compounds. Two distinct clinical patterns occur in children (LEAD POISONING, NERVOUS SYSTEM, CHILDHOOD) and adults (LEAD POISONING, NERVOUS SYSTEM, ADULT). In children, lead poisoning typically produces an encephalopathy. In adults, exposure to toxic levels of lead is associated with a peripheral neuropathy.
Poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of LEAD or lead compounds.
